The muscle makeup
Compartments
100
This type of muscle is attached to the skeleton
What is skeletal muscle.
100
This is the mid point of the I band
What is Z disc?
100
This is the "coming together" of the neuron and the muscle fiber.
What is the Neuromuscular Junction?
100
The outter most connective tissue layer of the whole muscle.
What is epimysium?
100
This muscle compartment (think AREA or section!) causes flexion at the elbow/shoulder?
What is the anterior arm?
200
This type of muscle is involuntary and works to contract the heart.
What is cardiac muscle?
200
The contractile unit of the myofibril.
What is the sarcomere?
200
The "space" between the terminal branch and the muscle fiber.
What is the synaptic cleft?
200
A bundle of muscle fibers.
What is a fascicle?
200
This muscle compartment causes adduction of the thigh.
What is the medial compartment of the leg?
300
This type of muscle has two "sections" which lay at right angles, and work together to create movement in hollow organs.
What is smooth muscle?
300
Thin filaments
What are actin filaments?
300
The neuron and any muscle cell it innervates.
What is the motor unit?
300
A bundle of muscle fibers is bound together by this.
What is perimysium?
300
This muscular compartment causes flexion of the spine.
What is the anterior trunk?
400
This type of muscle has a single nucleus and no striations.
What is smooth muscle?
400
The "overlap" section of the sarcomere, contains thick and thin filaments.
What is the A band?
400
In a neuromuscular junction, the neurotransmitter secreted at the terminal branch.
What is ACh (acetylcholine)?
400
A single muscle fiber is wrapped in this.
What is endomysium?
400
This muscular compartment causes extension of hip and flexion of the knee.
What is the posterior thigh compartment?
500
This type of muscle is striated, and has long, bundled muscle fibers.
What is skeletal muscle?
500
This area contains think filaments only (myosin).
What is the H zone?
500
The closed gate may be opened when ACh receptors grab the neurotranmitter. This gate opens the way for WHAT?
What is sodium to pass into the muscle fiber?
500
The two myofilaments within the myofibril, which slide past each other.
What are actin and myosin?
500
This muscular compartment causes plantflexion, inversion at ankle, and flexion of the digits.
What is the posterior compartment of the leg?
