Question 1
- The atlas is classified as a cervical vertebrae.
The Atlas is the first cervical bone (C1) of the vertebral column. It supports the base of the skull and links with Axis to form the atlanto-axial joint.
Question 2
- Which of the following is NOT a function of the skeletal system? All of the above are functions of the skeletal system.
Protection of vital organs. The ribs protect the mediastinum from blunt damages to the lungs & heart. The cranium also protects the soft brain from trauma.
Locomotion and support. The musculoskeletal system provides locomotion to the body. The pelvis provides support to the urogenital system.
Storage of inorganic salts. The skeletal system houses 97% of the calcium phosphate in our body which is an inorganic salt.
Question 3
- Improper administration of CPR can force the floating ribs into the liver, causing severe bleeding.
According to the American Health Association (AHA), hands should be interlocked between the nipples & the palm located at the end of the person's breastbone, where the ribs join together. Two fingers are then placed at the tip of the breastbone. To pump, press down 2 inches & allow full recoil.
Question 4
- When the epiphyseal plate is completely replaced by bone, long bones have reached their adult length.
The epiphyseal plate is hyaline cartilage found in the metaphysis (ends) of long bones. It is replaced by compact bone during growth plate fusion. This happens at the age of 14-19 for males & 12–16 for females.
Question 5
- The thickest intervertebral discs would be found in the lumbar region.
This is due to the weight-bearing capacity of the lumbosacral region. In contrast, you can find the thin intervertebral discs at the cervical region.
Question 6
- The only movable joint in the head is the temporomandibular joint
This is joined by the temporal bone to the mandible allowing a person to talk, chew, or move the jaw.
Question 7
- Compact bone is found in the diaphysis of long bones.
The diaphysis (mid part of a long bone) consists of strong compact bone, housing the bone marrow and protecting it from trauma.
Question 8
- The normal loss of bone that occurs with aging is osteoporosis
Osteoporosis happens when the bone is too porous and has lost its bone density over time, like aging. This may be slowed by calcium banking.
Question 9
- Red bone marrow functions in the formation of blood cells. This is found in the flat (pelvis, sternum) & spongy bones (femur).
Question 10
- While working as a forensic pathologist, you are given two sets of pelvic bones to examine. You are asked to determine which is male and which is female. Which of the following statements would NOT be true in making your determination?
- The pelvis with the greater pubic angle is male - Males: 50-82 degrees; Females: > 90 degrees
- The female pelvis is heavier than the male pelvis - The male pelvis is much heavier and thicker.
Question 11
- The body system responsible for synthesizing the Vitamin D necessary for calcium absorption is the integumentary system.
Sunlight exposure of the skin synthesizes the 7-dehydrocholesterol in the keratinocytes, then transformed to cholecalciferol & attached to a binding protein to be carried out to the circulation.
Question 12
- One role of fontanels is allow for compression of the skull during childbirth.
The fontanels allow the sutures of the cranium to let the bones overlap, especially during the passage of the baby at the birth canal.
Question 13
- Which of the following is NOT a component of the appendicular skeleton? Sternum
These are mostly composed of the bones of the extremities and to where they are attached, like femur, coxa, & humerus.
Question 14
- The lateral knob at the ankle is a projection of the fibula.
The lateral malleolus is formed from the distal part of the fibula, which is the 'ankle' felt at the lateral side.
Question 15
- The distal end of the tibia articulates with the talus.
Also called the talocrural joint, it joins the subtalar joint (talocalcaneal) & the inferior tibiofibular joint to form the ankle.
Question 16
- Skull bones are joined together by tight connections called sutures.
The sutures are fibrous joints that are flexible & strong enough that allow cranial bones to accommodate the growing brain of an infant. During late childhood, it becomes sturdy & prevents movement of cranial bones.
Question 17
- Which of the following is NOT a function of the axial skeleton? Provide movement
To provide movement is the function of the appendicular skeleton, like the extremities.
Question 18
- The bones of the limbs are classified as long bones.
They are called long bones because
- Longer shafts with bulky ends.
- Strong cortical bones but may also have spongy bone at the proximal ends.
Upper extremities: humerus, ulna, radius, metacarpals, & phalanges.
Lower extremities: femur, tibia, fibula, metatarsals, & phalanges.
