Semester 2 Final Flashcards
Muscle that acts in opposition to the action of another muscle
Antagonist
Wasting away, decrease in size
Atrophy
Shortening of muscle tissue
Contraction
Muscle disorder resulting from defective or faulty nutrition, abnormal development, infection
Dystrophy
Increasing an angle at a joint
Extension
Soft
Flaccid
Decreasing angle at a joint
Flexion
Muscle pain
Myalgia
Loss or impairment of motor function
Paralysis
Partial contraction, maintains posture
Muscle tone
Continued contraction of muscle
Tetanic
Groups of muscles contract in abnormal manner
Convulsion
Attitude or position of the body
Posture
Muscle that acts directly to bring about a desired movement
Prime mover
Active or passive movement of muscle groups to the fullest extent possible
Range of motion
Repeating units of muscle fibers with the ability to contract
Sarcomere
Pertaining to the frame work of the body
Skeletal
Any agent that produces a change in the development or function of tissue
Stimulus
Slight contraction of muscle
Tonus
Pertaining to any large interior organ in any one of the cavities of the body
Visceral
Muscle shortening produces movement through a full range of motion
Isotonic
Contraction/shortening of muscle with no joint movement
Isometric
Uncoordinated contraction of muscle fiber
Fibrillation
Involuntary contractions
Spasms
Involuntary nerves, maintains heart beat
Brain stem
Largest area of the brain
Cerebrum
Organic loss of intellectual function
Dementia
Convey information to the muscles and glands from the CNS
Efferent
Sudden pushing force
Impulse
Carry and process sensory info
Interneurons
3 membranes that surround/protect brain and spinal cord
Meninges
Chemical messenger, released from axon to neuron
Neurotransmitter
Specialization of nerve cell that determines impulse flow
Polarity
Involuntary action in response to stimulus
Reflex
Voluntary nerves
Somatic nervous system
Space between neurons
Synapse
