Quiz 5 - Skeletal Muscle Function

Question 1

characteristics of muscles

Answer 1

excitability - ability to respond to stimulation
contractility - ability to shorten or contract actively
extensibility - ability to be stretched or extended
elasticity - ability to recoil and resume its original length after being stretched

Question 2

types of muscle tissue

Answer 2

skeletal
smooth
cardiac

Question 3

skeletal muscle

Answer 3

attached to bone
striated 
elongated
multinucleate cells
allows locomotion and body movement

Question 4

smooth muscle

Answer 4

in walls of hollow organs (intestine, blood vessels, bladder)
nonstriated
mononucleate cells
forces blood and substances through body channels

Question 5

cardiac

Answer 5

in the heart
striated
monoculeated cells
allows heart to pump blood through blood vessels

Question 6

Skeletal muscle functions

Answer 6

produce movement
maintain posture
stabilize joints
generate heat

Question 7

producing movement

Answer 7

muscles pull on tendons and move bones for body movement

Question 8

maintain posture

Answer 8

enables us to maintain erect/seated posture - against gravity’s effects

Question 9

stabilize joints

Answer 9

supports the joints of the skeleton

Question 10

generate heat

Answer 10

contracing muscles generates heat, heat lost from muscles helps maintain our body temperature
