Bio Psy Kalat Muscles

QuestionAnswer
What are the 3 types of muscles? Smooth, Striate, and Cardiac
Smooth muscles are... involuntary and used in digestion, pupils, lungs and sweat glands
Striate or Skeletal muscles are... used to control movement of the body in relation to the environment
Cardiac muscles... have properties of both smooth and striate muscles
Neuromuscular Junction is the synapse where motor neuron meets a muscle fiber
In skeletal muscles... every axon releases acetylcholine at the neuromuscular junction and excites a muscle to contract
Each muscle can make... just one contraction in one direction
In the absence of excitation... a muscle will relax, but never moves actively in the opposite direction
For a muscle to work in two directions it takes... an antagonistic muscle (flexor/extensor in the arm)
Myasthevia Gravis is a disease where the immune system forms antibodies that attack the individuals own body. Attacks the acetylcholine receptors at the neuromuscular junction
Slow-twitch muscle fibers do not fatigue because they are aerobic and use oxygen during movement
Fast-twitch muscle fibers result in fatigue because they do not require oxygen (anaerobic)
Proprioceptor is a receptor that detects the position or movement of a part of the body. when a muscle is stretched, the spinal cord sends a reflexive signal to contract it
Muscle Spindle is a receptor parallel to the muscle that responds to stretch
Golgi Tendon is stimulated and acts as a brake or shock absorber to prevent contraction that is too quick or extreme
Infants have 3 types of automatic reflexes... Grasp-hand, Babinski-foot, and Rooting-cheek
Ballistic Movement is executed as a whole. Once initiated cannot be altered or corrected while in progress (stretch reflex or pupil dialation)
Central Pattern Generators neural mechanisms in the spinal cord or elsewhere that generate rhythmic patterns of motor output. Wet dog shake, wings, fins. the number of frequency of movement is controlled.
Motor Program either learned or built in to the nervous system. Mouse cleaning itself has a fixed sequence from beginning to end. Yawn, stretching.
