Auxillary structures of skeletal Muscle

Question 1

What is a Fascia

Answer 1

a sheet of fiborus connective tissue that is deep to skin and surrounds muscles and other organs of the body

Question 2

describe superficial fascia

Answer 2

seperates the muscle from the skin
provides pathway for nerves and vessles
stores fat and insulates
protects muscle from trauma

Question 3

what are the 2 types of fascia talked about in lecture?

Answer 3

Suprficial fascia and deep fascia

Question 4

describe deep fascia

Answer 4

-holds muscle with similar functions together
-allows free movement
-carries nerves and vessles
-fills space between muscle

Question 5

Part of fascia:
Epimysium

Answer 5

covers the entire muscle and holds fascile together

Question 6

Part of fascia:
perimysium

Answer 6

covers fascicle by going AROUND them

Question 7

Part of fascia:
endomysium

Answer 7

inside or WITHIN muscle fibers

Question 8

Tendon:

Answer 8

an extension of connective tissue that connect muscle to bone or to other muscle

Question 9

tendon proper
What it does?

Answer 9

does the connecting. conencts skeletal muscle to bone

Question 10

tendon sheath
what it does?

Answer 10

encloses tendons to allow them to slide back and forth easily

Question 11

Muscles are highly …..

Answer 11

vasculaur!!

Question 12

nerves that convey sensory information to the central nervous system are…

(afferent or effernt?)

Answer 12

afferent nerves

Question 13

nerves that convey impules for muscular contraction to spinal cord are ….
(afferent or efferent?)

Answer 13

efferent nerves

Question 14

2 types of muscle receptors

Answer 14

Muscle spindles and Golgi tendon organs

Question 15

Muscle spindle:
-where is it located on muscle?
-what does it pick up on?
-where does the information go to?
-what is the response?

Answer 15

-located INSIDE
-picks up on muscle LENGTH
-sends info to central nervous system
-response is muscle contraction

Question 16

Golgi Tendon Organ:
-where is it located on muscle?
-what does it pick up on?
-where does the information go to?
-what is the response?

Answer 16

-located by tendinous connective tissue at ENDS
-picks up on TENSION and change in tension
-sends info to spinal cord
-response is muscle contraction
