1refers to the skeletal system and constitutes constitutes 40-50% of total body weight
muscular system
2specialized tissue which converts chemical energy into mechanical work, thus muscles is instrument of action
muscular system
3the scientific study of muscles
myology
4muscle cells are called
muscle fibers
5help propel and mix food and water in the digestive tract, propel secretions from organs, regulate blood flow through vessel
smooth muscle
6heart to beat, propelling blood to all parts of the body
cardiac muscle
7widest part of the body
latissimus dorsi
8number of abdominal muscles
10
9largest part of the body
gluteus maximus
10longest part of the body
sartorius
11abbility to respond to certain stimuli
excitablity / irritability
12ability to transmit impulses
conductivity
13ability to shorten and thicken to generate to do work
contractility
14ability to be stretched without damaging the tissue
extensibility
15ability to return to its original form and shape after contraction
elasticity
16skeletal muscle cells
muscle fibers
17smallest amount of stimulus, enough to produce a muscle twitch
minimal/liminal (threshold)
18any stimulus sof lesser strength, a type of stimulus that cannot produce twitch
sub-minimal/subliminal (subthreshold)
19surround and protect the muscle tissue
connctive tissue
20large sheet like connective tissue that covers the entire muscle, bandage
fascia
21subcutaneous layer, hypodermis
superficial fascia
23cord of dense connective tissue that attaches muscle to a bone
tendons
24broad, flattened connective tissue that attaches muscle to another
aponuerosis
25white glistening fibrous bands of connective tissue which attach the muscle to the bone
tendons
26flat tendons are
aponeuroses
27less moveable attachement site, more stable end, usually proximal
origin
28more moveable attachement site, less stable end, usually distal
insertion
29persistent or continous state of slight muscle contraction
muscle tones
30defined as the tension in a muscle at rest
muscle tone
