Myology

Question 1

Muscle Tissue, 3 kinds:

Answer 1

Smooth
Cardiac striated
Skeletal striated

Question 2

Smooth Muscle

Answer 2

non striated, smooth
in blood vessels, airways, most organs
fx: paracentesis, vasoconstriction (involuntary movement)

Question 3

Cardiac Striated Muscle

Answer 3

striated, branching
heart
involuntary contraction and relaxation rythm

Question 4

Skeletal Striated Muscle

Answer 4

striated, many nuclei
everywhere (around skeleton)
move bones (voluntary)

Question 5

3 types of skeletal muscle

Answer 5

red Slow oxidative (Type 1)–resistant to fatigue
red Fast oxidative (Type 2a) – looks like type 1, acts like 2
white Fast-Glycolytic (Type 2b)- not fatigue resistant

Question 6

Fx of Muscle Tissue

Answer 6

Movement
Support and maintain posture
Heat production ie shivering

Question 7

Muscle the Organ

macroscopic view

Answer 7

Muscle Belly
Tendons
 Enthesis of Tendon-- dense regular c.t. between tendon and bone.  
ie bicep
fixed end at scapula
mobile end at antebrachium

Question 8

Micro Anatomy of a muscle
(connective tissue)

EPEF-any

Answer 8

Endomysium–surrounds muscle cells
Perimysium- surrounds endomysium units
Epimysium- surrounds perimysium (muscle)
Fascia- surrounds muscles as one

(fyi: on drawing endo’s extend past muscle cells, peri’s past that, and epi’s surround and extend past that)
