Question 1

During embryonic and fetal develop,most skeletal tissues arise from

Accepted Answer

Most skeletal tissues arise from mesenchymal cells, which are multipotent cells that can differentiate into various cell types including cartilage, bone, and muscle. The neurocranium and notochord do play important roles in skeletal development, but they do not give rise to most skeletal tissues. The endoderm primarily gives rise to the epithelial lining of the digestive, respiratory, and urogenital systems.

Question 2

The bones of the vertebrae are from the mesenchymal cells from

Accepted Answer

The vertebrae are derived from the mesoderm, which is one of the three primary germ layers in embryonic development. Mesenchymal cells from the mesoderm give rise to a variety of tissues, including bone and cartilage. Therefore, choice B is the best answer.

Question 7

Which pelvis in the diagram shows the characteristics of a female pelvis?

Accepted Answer

The female pelvis typically has a wider, more oval-shaped pelvic inlet, a broader pubic arch angle, and a shorter sacrum than the male pelvis. Pelvis A in the diagram shows these characteristics, while pelvis B has a narrow, heart-shaped pelvic inlet, a narrower pubic arch angle, and a longer sacrum, which are more typical of a male pelvis.

Question 8

Shoulder (glenohumeral)dislocations are very common in emergency care.Which statement best describes an anterior shoulder dislocation?

Accepted Answer

Anterior shoulder dislocation occurs when the humeral head moves out of the glenoid cavity and forward, which means it is in front of the glenoid cavity.

Question 9

Which of the following is a common condition experienced by runners,which is caused by the kneecap tracking laterally as well as inferiorly and superiorly.

Accepted Answer

Patellofemoral stress syndrome, also known as "runner's knee," is a common condition experienced by runners. It is caused by the kneecap tracking laterally (to the outside of the knee) as well as inferiorly (downward) and superiorly (upward). Symptoms include pain around or behind the kneecap, especially when bending the knee or going up or down stairs.

Question 10

Which of the following is NOT a way that the skeletal system contributes to homeostasis?

Accepted Answer

The skeletal system does not store or release sodium ions. This task is primarily the responsibility of the kidneys and the endocrine system. The other options describe ways that the skeletal system contributes to homeostasis by providing structural support, producing blood cells, protecting vital organs, and facilitating movement.

Question 14

Which of the following is a condition where the foot is twisted inferiorly and medially,and the angle of the arch is increased?

Accepted Answer

The condition described is called clubfoot, which is a congenital condition where the foot is twisted inward and downward with an increased angle of the arch.

Question 15

The boundary between the true pelvis and the false pelvis is the

Accepted Answer

The boundary between the true pelvis (pelvis minor) and the false pelvis (pelvis major) is the pelvic brim, also known as the pelvic inlet. The pelvic brim is defined by the sacral promontory posteriorly, the arcuate line laterally, and the superior border of the pubic symphysis anteriorly.

Question 16

In the diagram,which labeled bone is the only bone of the foot that articulates with the fibula and tibia?

Accepted Answer

The labeled bone B is the only bone of the foot that articulates with the fibula and tibia, forming the ankle joint. Bone A is the talus which sits on top of bone B and articulates with the tibia and fibula as well. Bone C is the calcaneus, commonly known as the heel bone. Bones D and E are the navicular and cuboid respectively, which do not articulate with the tibia or fibula.

Question 17

The neurocranium gives rise to bones of the

Accepted Answer

The neurocranium, which is the portion of the skull that surrounds and protects the brain, gives rise to the bones of the skull. Therefore, the best choice is E. The other options listed are incorrect, as the upper and lower limbs come from the appendicular skeleton, the face from the viscerocranium, and the ribcage from the axial skeleton.

Question 18

Which of the following is a condition where the medial longitudinal arch of the foot is decreased,resulting in fallen arches?

Accepted Answer

Flatfoot, also known as pes planus, is a condition where the medial longitudinal arch of the foot is decreased or absent, resulting in fallen arches. This can lead to pain, discomfort, and difficulty with certain activities. Patellofemoral stress syndrome is a condition where there is pain around the kneecap, bunions are bony bumps that form on the joint at the base of the big toe, clawfoot is a condition where the toes are bent like claws, and clubfoot is a birth defect where the foot is twisted out of shape or position.

Question 19

Absorption of calcium and phosphate from the [dropdown 1] system provide minerals for bone formation.Hormones,like estrogen,from the [dropdown 2] system influence growth of long bones in the appendicular system.Vitamin Ds active form is finalized in the kidneys of the [dropdown 3] system,which helps promote calcium absorption.The tuberosities on long bones provide attachment sites for tendons in the [dropdown 4] system.White blood cells,which are formed in marrow of long bones,contribute to the [dropdown 5] systems function.

cardiovascular
digestive
integumentary
lymphatic
muscular
reproduction
respiratory
urinary
