Exam 1 Flashcards
Integration
To process and interpret sensory input and decide if action is needed
Motor output
A response to integrated stimuli and their sponsor activates muscles or glands
Central nervous system function
Integration command center
interpret incoming sensory information and
issues outgoing instructions
Peripheral nervous system functions
Service communication lines among sensory organs the brain and spinal cord and glands or muscles
Sensory division (afferent)
Nerve fibers that carry information to the CNS
Motor division (efferent)
Nerve fibers that carry impulses away from the central nervous system
Somatic nervous system (voluntary)
Consciously controls the skeletal muscles
Autonomic nervous system (involuntary)
Automatically control smooth and cardiac muscles and glands
further divided into the sympathetic and parasympathetic nervous system’s
What are neurons
They are nerve cells that specialize to transmit messages
What are the two major regions of neurons
So body – nucleus and metabolic center of the cell
processes – fibers that extend from the cell body
What are dendrites and what do they do
They conduct impulses toward the cell body neurons may have hundreds of dent rites
What are axons and what did I do
Axons conduct impulses away from the cell body
neurons have only one axon arising from the cell body at the axon hillock
Sensory input
To monitor changes occurring inside and outside of the body
