Muscle Terminology
the only type of muscle that is voluntary
What are skeletal musclels
A single stimulus is delivered to a muscle; the muscle contracts and then fully relaxes
What is a muscle twitch
What is the number of layers a muscles contains?
What is muscle body, Fascicle, Muscle Fibers or cells, Myofibrils)
The primary purpose of the muscular system
What is movement
What is the origin of a muscle?
The place where the muscle begins, also where the muscle contracts towards.
nonstriated and involuntary muscle type
What is smooth muscle
The motor neuron and muscular motor endplate interconnect here.
What is the neuromuscular junction
layer of connective tissue that surrounds the skeletal muscle
What is epimysium
the basic need for all muscle movements
ATP
The series of contractile units that make up each myofibril; extends from z line to z line
What is sarcomere?
The nerve impulse when reaching the axon terminal causes the vesicles to release this neurotransmitter.
What is acetylcholine ACh
Layer of connective tissue that separates a muscle into smaller bundles; surrounds fascicles
What is Perimysium
In what two ways can the human body make ATP?
adding a phosphate group from creatine phosphate storage; Cellular respiration (converting glucose to ATP)
The chief muscle in each muscle group movement
What is the prime mover
The flat, sheet-like fascia that attaches muscle covering to muscle coverings; muscle to muscle or muscle to bone.
What are aponeuroses
The electrical signal or nerve impulse travels along the _______________ of the muscle cell and penetrates deep into the muscle tissue by the _____________________________.
What is sarcolemma and transverse tubules
the cellular organelle in muscle fibers that store and release and recapture calcium
What is the sarcoplasmic reticulum
The anaerobic stage of cellular respiration and the aerobic stage of cellular respiration.
What is glycolysis and citric acid cycle
The frequency of stimulation to a muscle is increased in a pulsing state; the muscle is unable to relax fully before it begins to contract for a second and third time.
What is summation
The perpendicular extension of the sarcolemma that penetrates into the interior of the muscle
What are the transverse tubules
The nerve impulse stimulates the sarcoplasmic reticulum to release ______________ into the sarcomere, activitating the _____________ on the myosin filament, causing a ______________________.
What is calcium; crossbridges; muslce contraction
Enlarged portions on the sarcoplasmic reticulum found on either side of the transverse tubules
What are cisternae
The by product of muscle contractions
What is heat
What 5 functions does the Skeletal Muscle Tissue provide?
Movement (skeletal muscle), Protection (over organs), Posture (bipedal motion), Guards entrances and exits (sphincter), Thermoregulation (homeostasis).
