Components of Nervous System
Brain and Spinal Cord
Think and Move
Two Main Subsystem
Central Nervous System (CNS) Peripheral Nervous System (PNS)
CNS contains
Brain and Spinal Cord
Think and Move
PNS contains
All nervous tissue outside the brain and spinal cord
Peripheral everything outside
3 basic functions of Nervous System
Sensory, Intergrative, and Motor
Sensory functions does what?
Decect stimuli
When your eyes see something or your hands or touch a warm surface, the sensory cells, also known as Neorons, send a message straight to your brain.
Intergrative does what?
Analyze and store sensory info
vis best known as the interpretation of things you have felt, tasted, and touched with your sensory cells
Motor does what
Responds to intergrative decision
Once your brain has interpreted all that you have learned, either by touching, tasting, or using any other sense, then your brain sends a message through neurons to effecter cells, muscle or gland cells, which actually work to perform your requests and act upon your environment.
Sensory (afferent) Neurons provides
(input) information from the environment to the body
when you touch a hot surface, a sensory neuron informs your body that the temperature near your skin is rising.
Motor (efferent) Nerons carry
output from the CNS to the PNS
PNS is subdivided into
Somatic and Automatic Nerve System
SNS deals with ______ movements and contains ___ muscles.
Voluntary skeletal
ANS deals with _______, an convey impulses CNS to ______ _______ ______, _______ _______ ________, and _________
Smooth muscle tissue, Cardiac muscle tissue, and glands.
Salivation, perspiration, diameter of the pupils, micturition - (the discharge of urine), and erection are also controlled by the ANS
The Nevous system consit of two types of cells which is ______ and ___________
Neuron and Neurogila
Neurons usally have 3 parts
Cell body, dendrites,and a single axon
recieving or input portion of a neuron.
Little trees
An axon or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron's cell body or soma.
long and slender
Cell body contains a
nucleus surrounded by the cytoplasma that includes typical organelles
supports and protect neurons
5 main types of Neurons are
Astrocytes, Oligodendrocytes, mircrogila, and ependynal cells found in CNS
