Nervous System - ANSWER This controls and integrates all body activities within limits
that maintain life
Three basic functions:
-sensing changes with sensory receptors (fullness of stomach or sun on your face)
-interpreting and remembering those changes
-reacting to those changes with effectors (muscular contractions and glandular secretions)
Brain - ANSWER _______, cranial nerves, spinal cord, spinal nerves, ganglia, enteric
plexuses and sensory receptors are the major structures of the nervous system
Central Nervous System (CNS) - ANSWER This consists of the brain and spinal cord
Peripheral Nervous System (PNS) - ANSWER This consists of cranial and spinal nerves
that contain both sensory and motor fibers
All nervous tissue outside the CNS
Connects CNS to muscles, glands and all sensory receptors
Somatic Nervous System (SNS) - ANSWER Voluntary
Neurons from cutaneous and special sensory receptors to the CNS
Motor neurons to skeletal muscle tissue
Autonomic Nervous System (ANS) - ANSWER Involuntary
1
, Sensory neurons from visceral organs to CNS
Motor neurons to smooth and cardiac muscles and glands
Sympathetic division-speeds up heart rate
Parasympathetic division-slows down heart rate
Enteric Nervous System (ENS) - ANSWER Involuntary sensory and motor neurons
control GI tract
Neurons function independently of ANS and CNS
Neurons - ANSWER Functional unit of nervous system
Have capacity to produce action potentials-electrical excitability
Cell body-single nucleus, neurofilaments give cell shape and support, microtubles move
material inside cells
Cell processes=dendrites and axons
Dendrites - ANSWER Part of a neuron
Conducts impulses towards the cell body
Typically short, highly branched, and unmyelinated
Surfaces specialized for contact with other neurons
Axons - ANSWER Part of a neuron
Conduct impulses away from cell body
Long, thin cylindrical process of cell
Arises at axon hillock
End in fine processes called axon terminals
Swollen tips called synaptic end bulbs contain vesicles filled with neurotransmitters
