Muscle + Nervous Tissue

Question 1

Skeletal muscle

Answer 1

• Long + cylindrical cells/ striated
• attach to bones and move by contracting and relaxing in response to voluntary messages from the NS

Question 2

Smooth muscle

Answer 2

• non striated/ involuntary
• propels substances along internal passageways
• lines hollow organs to help squeeze substances through

Question 3

cardiac muscle

Answer 3

• striated /involuntary
• lines the walls of the heart to propel blood through blood vessels to other parts of the body
• only found in myocardium

Question 4

nervous tissue

Answer 4

Transmit electrical signals from sensory receptors to effectors

Question 5

Tissue healing: regeneration

Answer 5

Proliferation of cells and tissue. Complete restoration of lost tissue structures

Question 6

Tissue healing: repair

Answer 6

Proliferation of cells and tissue, and the formation of scar tissue. Tissue structure is not completely restored. E.g., too much damage, or can’t be repaired.

Question 7

STRONG REGENERATIVE CAPACITY

Answer 7

Epithelial tissue, bone, dense irregular connective tissue, blood-forming tissue

Question 8

MODERATE REGENERATIVE CAPACIT

Answer 8

Smooth muscle, dense regular connective tissue.

Question 9

WEAK REGENERATIVE CAPACITY

Answer 9

Skeletal muscles, cartilage.

Question 10

NO REGENERATIVE CAPACITY

Answer 10

Nervous tissue, cardiac tissue.

Question 11

stem cells

Answer 11

(1) can divide over and over again to produce new cells

(2) as they divide, they can change into the other types of cells that make up the body

Question 12

The image below shows a photomicrograph of tissue. What best identifies the tissue shown?

Answer 12

Smooth muscle tissue would function to propel substances or objects in hollow organs.
