Cayce Ch.6 Muscles

For Mrs. Eastham Anatomy

QuestionAnswer
Contractility ability of skeletal muscle to shorten with force
Excitability capacity of skeletal muscle to respond to a stimulus
Extensibility ability to be stretched
Elasticity ability to recoil to their original resting length after they have been stretched
Three types of muscle skeletal, smooth, cardiac
connective tissue sheath that Surrounds each skeletal muscle epimysium
loose connective tissue located outside the epimysium; surrounds and separates muscles Fascia
visible bundles that make up muscles fasciculi
loose connective tissue that surrounds the fasciculi perimysium
single muscle cells that make up fasciculi
each fiber is surrounded by a connective tissue sheath called endomysium
cytoplasm of each fiber is filled with___, a threadlike structure that extends from one end of the fiber to the other myofibrils
Myofibrils contain these 2 major types of protein fibers(myofilaments) actin(thin) and myosin(thick)
Actin and Myosin myofilaments form highly ordered units called sarcomeres
basic structural and functional unity of the muscle sarcomeres
the charge difference across the membrane resting membrane potential
the brief reversal back of the charge is called action potential
nerve cells that carry action potentials to skeletal muscle fibers motor neurons
Axons enter muscles and branch
Each branch that connects to the muscle forms a ___ or ___ near the center of the cell neuromuscular junction or synapse
A single motor neuron and all the skeletal muscle fibers it innervates are called a motor unit
the enlarged nerve terminal is the presynaptic terminal
the space between the presynaptic terminal and the muscle cell is the synaptic cleft
the muscle fiber (in nerves) postsynaptic terminal
each synaptic terminal contains synaptic vesicles
synaptic vesicles secrete a neurotransmitter called acetylcholine
