Objective 1

Question 1

Where is Skeletal Muscle Tissue attached?

Answer 1

Skeletal Muscle Tissue attaches to and covers the bony skeleton; attached to skin in some regions

Question 2

Describe the cell structure of Skeletal Muscle Tissue

Answer 2

Skeletal Muscle Tissue has long, cylindrical multi-nucleated cells;

striated (has stripes=striations)

Question 3

Describe the function of Skeletal Muscle Tissue?

Answer 3

Skeletal Muscle Tissue engages voluntary control (conscious control)

• Maintains upright posture, locomotion, manipulation of the environment, facial expression
• Generation of heat (~60% of muscle energy is given off as heat) to maintain core temp.

Question 4

How does skeletal muscle tissue help control dangerous levels of heat?

Answer 4

Dangerous levels of heat are dissipated by dilation of cutaneous blood vessels

and activation of eccrine sweat glands

Question 5

What are the skeletal muscle receptors?

Answer 5

Nicotinic (ACh)

Question 6

Where is Cardiac Muscle Tissue located?

Answer 6

Cardiac Muscle Tissue occurs only in the walls of the heart

Question 7

Describe the cell structure of Cardiac Muscle Tissue

Answer 7

Cardia Muscle Tissue cells are branching, short, 1-2 nuclei / cells; striated;

connect at junction known as the intercalated disc

Question 8

Describe the function of Cardiac Muscle Tissue

Answer 8

Cardiac Muscle Tissue engages involuntary control

(self-generating contractions with autonomic influence)

• propells blood into circulation

Question 9

What are the Cardiac Muscle Tissue receptors?

Answer 9

Muscarinic (ACh) and Beta (NE)

Question 10

Where is Smooth Muscle Tissue located?

Answer 10

Smooth Muscle Tissue is located in the walls of hollow visceral organs,

such as the stomach, urinary bladder, and respiratory passages

Question 11

Describe the cell structure of Smooth Muscle Tissue

Answer 11

Smooth Muscle Tissue cells are spindle-shaped cells with a central nucleus;

no striations;

cells are arranged in sheets
