What is the largest part of the brain?
cerebrum
the basic unit of nervous system
nerve cell or neuron
Spinal Nerves and Cranial Nerves are located
Where is Peripheral Nervous System
the part that connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure
brainstem
Involves Involuntary Responses to Internal Stimuli
Autonomic Nervous System
what are the two types of neurons?
motor neurons and sensory neurons
Name the two divisions of the Nervous System
CNS & PNS
receives messages from other nerve cells
dendrites
Three parts of the Brain
cerebrum, cerebellum, brainstem
detect light, sound, odor, taste, pressure, and heat and send messages about those things to the brain
Sensory Neurons
transmit messages from the brain to the muscles to generate movement
motor neurons
what are the 3 main parts of the spinal cord
cervical, thoracic, lumbar
the nerve fibers that carry information into and out of the brain
cranial nerves
Conscious control of skeletal muscles
Somatic Nervous system
the nerves that carry motor and sensory signals between the spinal cord and the body
it maintains the body functions and restores the body to normal or relaxed mode
parasympathetic
major functions of the spinal cord
carrying signals from the brain, carrying information to the brain, reflex responses
Communication of the Peripheral Nervous System is by way of
Spinal Cord
Resting & Digesting, Fight or Flight
Sympathetic Division
axons release the chemical signal with chemical messengers called?
neurotransmitters
what does axons do?
transmit messages from the cell body to dendrites
