Ch10 Flashcards
A connective tissue partition that separates adjacent fasciculi in a skeletal muscle.
Perimysium
A dense layer of collagen fibers that surrounds a skeletal muscle and is continuous with the tendons/aponeuroses of the muscle and with the perimysium.
Epimysium
A small bundle; usually refers to a collection of nerve axons or muscle fibers.
Fascicle
A delicate network of connective tissue fibers that surrounds individual muscle cells.
Endomysium
Byronic stem cells that function in the repair of damaged muscle tissue
Myosatellite Cells
A collagenous band that connects a skeletal muscle to an element of the skeleton.
Tendon
A broad tendinous sheet that may serve as the origin or insertion of a skeletal muscle.
Aponeurosis
The plasma membrane of a muscle cell.
Sarcolemma
The cytoplasm of a muscle cell.
Sarcoplasm
The transverse, tubular extensions of the sarcolemma that extend deep into the sarcoplasm, contacting cisternae of the sarcoplasmic reticulum.
Transverse tubules
Organized collections of myofilaaments in skeletal and cardiac muscle cells.
myofibrils
A cytoskeletal filament in a skeletal or cardiac muscle cell; consists of actin, troponin, and tropomyosin.
Thin filaments
A cytoskeletal filament in a skeletal or cardiac muscle cell; composed of myosin with a core of titin.
Thick filament
A myosin head that projects from the surface of a thick filament and that can bind to an active site of a thin filament in the presence of calcium ions.
Cross bridge
A synapse between a neuron and a muscle cell.
Neuromuscular junction
