1
four types of muscle tissue that make up muscles
skeletal, nervous, connective
2
what are three types of muscle tissue?
skeletal, smooth, cardiac
3
what is fascia?
dense CT, covers each muscle
4
What is a tendon?
dense, CT, holds muscle to bone
5
What is a sarcolemma?
Muscle cell membrane
6
What is sarcoplasmic reticulum?
Tubulus for transport inside muscle fiber
7
What is transverse tubules?
Tubes that transport calcium from outside of cell to SR
8
what is an acetylcholine?
Neurotransmitter release the stimulate contraction of muscle fiber
9
Describe a neuromuscular junction
connection between motor, neuron and muscle fiber
10
what is acetylcholinesterase?
found at post synaptic, near muscular, junctions, and muscles and nerves
11
what is calcium?
Ion needed for muscle contraction, binds to troponin
12
What is troponin?
protein that holds tropomyosin in place that will bind with calcium
13
what is actin?
Thin filament, covered by tropomyosin
14
what is myosin?
Thick filament, wants to bind to actin
15
What is tropomyosin?
Rope like fiber, wrapped around Actin, covers binding sites for myosin
16
what is ATP
Chemical energy needed to power energy contraction
17
What is creatine phosphate?
Give the muscles an initial source for regenerating ATP
18
what is aerobic?
Process of cellular respiration that takes place in the presence of oxygen gas
19
What is anaerobic?
The process in which incomplete oxidation of glucose occurs in absence of oxygen
20
What is glycolysis?
The process in in which glucose is broken down to produce energy
21
What is oxygen debt?
Amount of oxygen required to restore body to pre-workout conditions
22
what is the process of contraction?
the SR and the tt release calcium into the synaps, calcium binds to troponin, troponin moves and drags the tropomyosin, it reveals myosin binding sites aka actin and then the myosin connects to the actin.
