Question 1

Which type of osseous tissue is porous and consists of trabeculae that form a lattice structure?

Accepted Answer

Cancellous bone is porous osseous tissue that consists of trabeculae that form a lattice structure. This type of tissue structure allows the storage of fat and bone marrow and provides strength to the bone.

Question 2

What type of osseous tissue makes up the Haversian system and comprises up 80% of skeletal mass?

Accepted Answer

Compact, or cortical, bones make up the Haversian system and comprise up to 80% of skeletal mass. This type of osseous tissue is located near the outer layer of the bone, and is made up of bone cells, nerves, blood and lymph vessels.

Question 3

In what location does hematopoiesis and storage of calcium and phosphate occur?

Accepted Answer

Hematopoiesis and calcium and phosphate storage occur in osseous tissue. Hematopoiesis, or the creation of red and white blood cells, mostly occurs in cancellous bone due to its make-up, which is more supportive of physiological functions than of structural ones.

Question 4

What occurs at the epiphyseal plate?

Accepted Answer

Ossification occurs at the epiphyseal plate. This is the process of longitudinal bone growth which occurs when cartilage at the end of the bone is replaced with bone.

Question 5

What substance is an inelastic tissue composed of protein and is a structural part of all living tissue?

Accepted Answer

Collagen is an inelastic tissue composed of protein and is a structural part of all living tissue. Collagen has a great amount of tensile strength and makes up tendons.

Question 6

Which tissue composed of collagen can be found in sheets, cords or band-like structures?

Accepted Answer

Ligaments are composed of collagen and can be found in sheets, cords or band-like structures. They are similar to tendons in their internal structure and strength, but they also contain elastin, which makes them stretch safely and still return to their normal shape.

Question 7

What type of tissue has a form called serous, which is fluid-filled?

Accepted Answer

Fascia is the tissue that has a form call serous, which is fluid-filled. This type of fascia makes up protective membranes that cover the internal viscera. Other types of fascia that do not have specific names relating to their functions are superficial and deep fascia.

Question 8

Which of the following is not a function of fascia?

Accepted Answer

Fascia does not assist in the conduction of the action potential from the nervous system to a muscle to make it move. All other answers correctly describe the three functions of fascia.

Question 9

Which of the following decreases bone health in the elderly, increasing the risks involved in falling?

Accepted Answer

Bone formation is outpaced by resorption in the elderly, causing decreased bone density and an increase in the risks associated with falling.

Question 10

Which organ system is responsible for transport of nutrients, removal of waste and overall environmental maintenance to support the body's function?

Accepted Answer

The cardiovascular system is responsible for transport of nutrients, removal of waste and overall environmental maintenance to support the body's function.

Question 11

What is the correct term for the amount of blood pumped out by the left ventricle during one beat of the heart?

Accepted Answer

Stroke volume is the amount of blood pumped out by the left ventricle during one beat of the heart. This, along with the heart rate, helps to determine overall cardiac output.

Question 12

All of the following are components of the heart's electrical conduction system EXCEPT:

Accepted Answer

Catecholamines are not part of the heart's electrical conduction system. They are hormones that assist in the contraction of the ventricle and increased emptying of the heart.

Question 13

How do the parts of a lever apply to principles of exercise in the body?

Accepted Answer

In exercise principles in the body, the parts of a lever operate as follows: joints are the axis, skeletal muscle contractions cause force to be applied, and the moving portion (limb and any weights carried) are the resistance. Any time the location of the resistance changes in reference to the axis, the exercise can be progressed or regressed.

Question 14

Which type of lever has the resistance between the effort force and the axis of rotation with the force arm greater than the resistance arm?

Accepted Answer

A second-class lever has the resistance between the effort force and the axis of rotation with the force arm greater than the resistance arm. An example is the way a wheel barrow is configured.
