Chapter 6 Flashcards
Chemical transmitter substance released by certain nerve endings.
Acetylcholine
Move away from the midline of the body
Abduct
A contractile protein of muscle
Actin
Electrical event occurring when a stimulus of sufficient intensity is applied to a neuron or muscle cell, allowing sodium ions to move into the cell and reverse polarity.
Action potential
Move toward the midline of the body
Addiction
Respiration in which oxygen is consumed and glucose is broken down entirely
Aerobic respiration
Transformation of glucose to private when limited amounts of O2 are available.
Anerobic glycolcysis
Muscles that act in opposition to an agonist or prime mover.
Antagonist
Fibrous or membranous sheet connecting a muscle and the part it moves
Aponeuroses
Organic compute that provides a quick energy for source for muscle fibers.
Creatine phosphate
Up and down movement that includes lifting the foot so that you’re standing on your heels
Dorisflexion
Movement that increases the angle of a joint
Extension
Muscles that immobilize a joint or bone.
Fixators
Bending, decreases the angle between bones
Flexion
Movable attachment of a muscle as opposed to its origin
Insertion
Product of anaerobic metabolism, especially in muscle
Lactic acid
Motor neuron and all the muscle cells it supplies
Motor unit
Contractile organelles found in the cytoplasm of muscle cells
Myofibrils
Principal contractile Protein found in muscles
Myosin
Region where a motor neuron comes into close contact with skeletal muscle cell
Neuromuscular region
Chemical released by neurons that may, binding upon receptors of neurons or affected stimulate or inhibit them
Neurotransmitter
Attachment of a muscle that remains fixed during muscular transaction
Origin
Volume of oxygen required to after exercise to oxide lactic acid formed during exercise
Oxygen debt
Sole of the foot
Plantar flexion
Muscles whose contraction are primarily responsible for a particular movement
Prime mover
Inward rotation of the forearm causing the radius to cross over the ulna
Supination
Fluid filled space at a synapse between neurons
Synaptic cleft
Muscles cooperating with another muscle or muscle group to produce a desired movement
Synergist
Cord of dense fibrous tissues attaching muscle to bone
tendons
