Skeletal Muscle

motor end plate

Area of sacrolemma across from synaptic end bulbs of axon terminal ; contains neurotransmitter receptors

Perimysium

Connective tissue covering surrounding a fascicle

Endomysium

Connective tissue covering surrounding individual muscle fibers

Epimysium

Connective tissue covering surrounding the muscle

axon terminal

Divides into synaptic end bulbs at neuromuscular junction

T Tubles

Finger like invagivations of plasma membrane

Synaptic vesicle

Found in synaptic end bulbs of axon terminal ;contains neurotransmitter molecules

synaptic end bulb

Parts of axon terminal that form neuromuscular junction

Sarcolemma

Plasma membrane of skeletal muscle fiber

Myofibrils

Rod like structures within skeletal muscle fiber that contain thin and thick filaments organized into sarcomers

Sarcomere

Smallest contractile unit within individual muscle fibers

synaptic cleft

Space between synaptic end bulbs of axon terminal and sarcolemma

Sarcoplasmic Reticulum

Stores calcium within muscle fiber

Triad

Two terminal cisternae and a T tubule
