What is a fiber?
Covering of an individual muscle cell
What is the endomysium?
A bundle of muscle fibers
What is a fascicle?
Connective tissue covering of a
fascicle
What is the perimysium?
Broad sheet of connective tissue that
attaches muscles to bones indirectly or
to other muscles
What is an aponeurosis?
Type of muscle with striations, multiple
nuclei, attached to the skeleton, and are
voluntary
What is skeletal muscle?
The contractile unit of a muscle cell, or
the space between 2 Z lines
What is a sarcomere?
Neurotransmmitter that initiates
muscular contraction
What is acetylcholine or Ach?
Part of the muscle cell which stores
Calcium before and after contraction
What is the sarcoplasmic reticulum?
One neuron and all the muscle cells that
it stimulates
What is a motor unit?
Muscle that closes, purses and protrudes
the lips in a kissing action
What is the orbicularis oris?
Muscle that raises the eyebrows and
wrinkles the forehead
What is the frontalis?
Muscle that inserts on the heel by the
Achilles tendon, or calf muscle
What is the gastrocmemius?
Muscle of the abdominal wall named for
direction of fibers
What is the rectus abdominus or
oblique?
A spasm of this muscle might give you a
“crick” in your neck
What is the sternocleidomastoid?
Extreme soreness in joints and skeletal
muscle caused by repetitive action or
trauma, common in the elbow
What is tendinitis?
Protrusion of an organ through an

What is a hernia?
A fatal genetic disorder that appears in

specific areas, usually strikes women in
their 30s to 40s.
What is fibromyalgia?
Extreme pain in the heel, caused by
trauma or excessive use
What is plantar fasciitis?
Filaments that are made of myosin, have
“heads”, and form cross bridges with
actin, allowing them to join together
What are thick filaments?
Type of respiration that produces 2 ATPs
and lactic acid, good for a sprint
What is anaerobic respiration?
Name of the theory that explains muscle
contraction and is what generates the
mechanical force of contraction
What is the Sliding Filament Theory?
Substance that exposes the myosin
binding sites on actin filaments,
allowing myosin and actin to attach
What is calcium?
Reason for the striations in skeletal
muscle
A or dark bands and I or light bands
The main function of muscle tissue
What is movement?
Connective tissue structure that attaches
muscle to bone
What is a tendon?
Type of contraction in which muscle
filaments slide past each other and the
muscle contracts, causing movement
What is isotonic?
Type of contraction in which muscles do
not actually shorten, like pushing against
a wall
What is isometric?
State of sustained partial contraction
which is vital to health
What is muscle tone?
In a contraction, the ___ bands
get smaller, the ____ zones
disappear, and the ___ bands
move closer together but don’t
change in length
