| 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\ |
