Hello, hello, my dear anatomy students! How are they? Welcome to another new anatomical video on this channel, Easy Anatomy, by Juan José Sánchez.
Today I bring you a trivia video. I ask you, how much do you know about the skeletal system? Join me in this simple video where, through 30 questions, you will be able to know if you have mastered or not mastered the large anatomy, the macro anatomy of the skeletal system.
So, first question, how many bones make up the human skeleton? 602 bones, 206 bones or 262 bones? The correct answer is 206 bones make up the adult skeleton.
Remember that the child may have bones that are not yet ossified and, therefore, the score will be a little different. Second question, what type of bones are ribs? Irregular bones, long bones or flat bones?
Correct, the ribs are considered flat bones even though they are very long in length, they do not meet the criteria to be considered long bones. Next question, how many cervical vertebrae do humans have? 5 vertebrae, 7 vertebrae or 12 vertebrae?
The correct answer is 7 cervical vertebrae found in the neck region that are named with the letter C from top to bottom, these being C1, C2, C3 and so on until reaching the C7 vertebra. Next question, where is the sphenoid bone located? In the thorax, in the lower limb or in the skull?
The correct answer is in the skull. The sphenoid bone is a single, central bone that is part of the base of the skull. Next question, what type of bones are considered vertebrae?
Flat bones, short bones or irregular bones? The correct answer is irregular bones. The vertebrae, if you see them, do not have a defined shape to say that it is a long bone, to say that it is a short bone or to say that it is a flat bone, so we call it an irregular type bone.
Next question, where is the vomer bone, also called vomerian bone, located? In the orbit, in the upper limb or in the nasal cavity? The correct answer is in the nasal cavity.
The vomer bone is a single, central bone that is located separating both nasal cavities because it is part of what we know as the nasal septum. Next question, where is the sacred bone, known as the sacral bone, located? In the skull, in the lower limb or in the spine?
Okay, the correct answer is in the spine. At the very bottom of the spine, just before the tailbone, we find this wedge-shaped bone called the sacrum bone. Let's continue then with the next question called, what are the bones of the leg?
Reminding them that the leg is the region between the knee and the ankle. We have radius and tibia, we have radius and ulna, and we have tibia and fibula. Don't get away from the video, after the presentation I'll tell you what the answer is.
[Music] It is vitally important that you subscribe to the channel so that you can access more trivia and access the more than 330 anatomy videos found there. If you want any particular trivia about a body system, don't forget to leave it in the comments. So, we were left with this question, the answer to which is tibia and fibula.
They are the two bones found in the leg region. Next question, how many bones make up the tarsus? Six bones, eight bones or seven bones?
The correct answer is seven bones. These bones, namely, are the talus, calcaneus, scaphoid, cuboid and the three cuneiform bones, also called cuneiform bones. Next question, what is the main mineral that makes up bones?
Calcium, phosphorus or magnesium? The correct answer is calcium. In fact, the human body's main reservoir of calcium is in the bones.
They are composed mostly of calcium. That is its main mineral. Next question, what are the parts of the coxal bone?
Ilium, iliac and pubis, ileum, ischium and pubis, or iliac, ischium and pubis? This seems like a tongue twister. The correct answer is option 2.
The hip bone, also in green, It is known as the iliac bone and its three parts are the ileum, the ischium and the pubis. What is the central region of all long bones called? Diaphysis, epiphysis or metaphysis?
Very well, the correct answer is diaphysis, which is the region between the two ends of each long bone, the ends being called the epiphyses. Next question, what is the smallest bone in the human body? The phalanges, the stapes or the nasal bone?
The correct answer is the stirrup. This small bone found inside the middle ear is considered the smallest bone in the human body. It is also called the stapedial bone.
What are the parts of the sternum? The epiphysis, base and body, the manubrium, body and xiphoid process, or the apophysis, body and xiphoid process? The correct answer is option 2.
The manubrium, which is the most superior portion, the body of the sternum and the apophysis or appendix or xiphoid process, whatever you want to call it, the most inferior part. Next, what type of bone is the scapula? Remember that we also call the scapula the scapula.
Flat bone, an irregular bone or a wide bone? The correct answer is a flat bone. The scapula, which is one of the bones that make up the thoracic girdle or shoulder girdle, is located in the dorsal part of the thorax.
It is a flat type bone. Next question, what other name is the zygomatic bone known by? Malar bone, maxillary bone or mandibular bone or mandible?
The correct answer is malar bone. It is one of the bones that makes up the cheekbone, the region called the facial solid compendium. What are the bones of the middle ear, what we call the ossicular chain?
Temporal, malleus, incus, malleus, incus and stapes, or ethmoid, stapes, incus? Okay, the correct answer is hammer, anvil, and stirrup. Next question, where is the hyoid bone located?
In the neck, in the skull or in the pelvis? Correct, the hyoid bone is a bone that is literally floating in the neck, supported by ligaments that join it to bones at the base of the skull and through membranes that join it to the cartilages of the larynx. Next question, what type of bones are the phalanges of the fingers?
Long bones, short bones or flat bones? The phalanges of the fingers are called long bones, despite their small size, because they meet the condition of being longer than they are wide. Within the phalanx, for example, this example of the hand, we have the proximal and middle phalanges in blue, and the distal ones in yellow.
Apply the same names to the fingers of the lower limb. Next question, how many pairs of ribs do we have? 10 pairs, 12 pairs, 24 pairs?
The correct answer is 12 pairs of ribs, which would make a total of 24 ribs, well, 12 ribs on each side. Next question, where is the unguis bone located? In the thorax, in the upper limb or in the orbit?
The correct answer is in the eye socket. This unguis bone is also called the lacrimal bone, which you see is located in the most medial part of the eye orbit. Next question, which of the following bones is considered a pneumatic bone?
The occipital, the parietal or the maxillary bone? Correct answer, the maxillary bone. This maxillary bone has a cavity that is filled with air and all bones that have cavities filled with air are considered maxillary bones, as does the frontal, as does the ethmoid, as does the sphenoid and as does the temporal bone.
. Very well, where is the lunate bone located? In the hand, in the foot or in the skull?
Correct answer, in hand. This semilunar bone is one of the carpal bones and owes its name to the fact that when you see it from a lateral view it has a half-moon shape. Next question, what other name does the C2 vertebra have?
Axis, atlas or coccyx? Correct answer, axis or axis, this second cervical vertebra is below the C1 vertebra, which is what we call the Atlas. Well, axis really means axis because the first vertebra rotates on that 2 that C2 would be its axis, that's where the name comes from.
Next question, how many bones make up the neurocranium? 12 bones, 8 bones or 10 bones? Correct answer, 8 bones.
The neurocranium is the bones that protect the brain. From front to back we would have a frontal, two parietal, two temporal and an occipital. If they add up, there would be 6 bones in total.
Now, at the base of the skull, from front to back, we have the ethmoid and sphenoid to complete the 8 bones. Well, next question, how many bones make up the carpus? 6 bones, 8 bones or seven bones?
Correct answer, 8 bones make up the carpus, which are the scaphoid, lunate, pyramidal, pisiform, trapezius, trapezoid, capitate and hamate bone. Next question, what is the largest bone in the human body? The tibia, the femur or the humerus?
The correct answer is: the femur is considered the longest bone in the entire human body. Next question, where are the metacarpal bones located? In the hand, foot or chest?
If the carpal bones were in the hand, then the metacarpal bones are also located in the hand. They are the ones that follow the carpus and there are exactly five of them. Here they are marked in red.
Next question, How many vertebrae make up the spine? 24 vertebrae, 28 vertebrae or 26 vertebrae? The correct answer is 26 vertebrae divided into seven cervical vertebrae, 12 thoracic vertebrae for a total of 19, 5 lumbar vertebrae that would add up to 24, a sacral bone if we count it as one vertebra and a coccygeal bone if we count it as one.
In total, 26 vertebrae. Next question, what bones make up the thoracic girdle? Do we have a scapula and clavicle, a clavicle and a humerus, or a scapula and a humerus?
This thoracic girdle is also known as the shoulder girdle as it is made up of the posterior scapula and the anterior clavicle. This then was the entire trivia video about the skeletal system.
