Muscle Parts

Question 1

The space between the terminal button and the motor endplate

Answer 1

SYNAPTIC CLEFT

Question 2

What are the myrofibrils consisting of?

Answer 2

Sacromeres

Question 3

The two fibers in the Sacromere, thick & thin

Answer 3

thick: myosin thin: actin

Question 4

The chemical released from the vesicles in the terminal button once Calcium rushes in:

Answer 4

Acetylcholine

Question 5

The two structures that meed to form the synaptic cleft

Answer 5

Motor endplate

terminal button/axon terminal

Question 6

Tissue that covers the myrofibril

Answer 6

sarcoplasmic riticulum - absorbs calcium

Question 7

Where the muscle and the neurosystem meet

Answer 7

Neuromuscular junction

Question 8

The electric charge that is sent from the body of the neuron (the sensory system connected to the spinal cord and brain), through the axon to the terminal button.

Answer 8

Action Potential

Question 9

Tissue that covers the muscle fibers

Answer 9

Endomysium

Question 10

Tissue that covers the Fascicle

Answer 10

Perimysium

Question 11

Tissue that covers the muscle belly

Answer 11

Epimysium

Question 12

Tissue that covers the epimysium

Answer 12

Deep fascia

Question 13

Final step of muscle contraction

Answer 13

Myosin grabs the actin and pulls it inward. Sacromere gets shorter, therefore muscle belly gets shorter overall,

Question 14

What are the transverse tubercles (T-tubercles)?

Answer 14

The spaces (channels) in the muscle that take the electrical signal from the motor endplate and deeper into the muscle fibers, causing the sarcoplasmic reticulum to release stored Calcium into the myrofibrils
