Question | Answer |
the ability of skeletal muscle to shorten w force | contractility |
the capacity of skeletal muscle to respond to a stimulus | excitability |
the ability to recoil | elasticity |
Each skeletal muscle is surrounded by a connective tissue sleath called | Epimysium |
Another connective tissue located outside the epmysium | Fascia |
A muscle is composed of numerous visible bundles called fascilculi, which are surrounded by | Perimysium |
The fasciculi are composed of single muscle cells called | Fibers |
Each fiber is surrounded by a connective tissue sleath called | Endomysium |
The cytoplasm of each fiber is filled with, and also it is a thread like structure | Myofibrils |
thin myoofilaments | actin |
thick myofilaments | myosin |
actin and myosin myofilaments frim highly ordered units called | sacromeres |
The charge difference across the membrane is called | Resting membrane potiential |
The brief reversal back of the charge is called | Action potiental |
Nerve cells that carry action potentials to skeletal muscle fibers | Motor Neurons |
Each branch that connects to the muscles form | Neuromuscular junction |
A single motor neuron and all the skeletal muscle fibers it innervates are called | Motor unit |
the enlarged nerve terminal is | presynaptic terminal |
the space between muscle cell is | synaptic cleft |
synaptic vesicles secrets a neurotransmitter called | actetylcholine |
the sliding of actin myofilaments past myosin contraction | sliding filaments\ |
