Flashcards in Chapter 6 Deck (30):
The movement of a limb or other part away from the midline of the body, or from another part.
A chemical transmitter substance released by certain nerve endings.
A contractile protein
An 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 the polarity.
To move toward the midline of the body
Respiration in which oxygen is consumed and glucose is broken down entirely; water, carbon dioxide, and large amounts of ATP are the final products.
A metabolic process in which glucose is broken down without the use of oxygen.
Muscles that act in opposition to an agonist or prime mover.
Fibrous or membranous sheet connecting a muscle and the part it moves.
Found in muscle fibers but not other cell types
Lifting foot towards shin
Increase in angle between bones
Muscles to immobilize joints
Decreases the angle between bones
Moveable attachment of a muscle opposed to its origin
Product of anaerobic metabolism
Motor neuron and all of the muscle cells it supplies
Contractile organelles found in the cytoplasm of muscle cells
Principle contractile proteins
Where motor neurons come into close contact with skeletal muscle
Chemical released by neurons that may stimulate or inhibit them
Attachment of muscle
Amount of oxygen required after exercise to oxidize the lactic acid formed during exercise
Bottom of foot flexed
Muscle whose contractions are primarily responsible for a particular movement; agonist.
The inward rotation of the forearm causing the radius to cross diagonally over the ulna- palms face posteriorly
The outward rotation of the forearm causing palms to face anteriorly
The fluid-filled space at a synapse between neurons.
Muscles cooperating with another muscle or muscle group to produce a desired movement.
