Parts of the brain Flashcards
are individual cells in the nervous system that receive, integrate, and transmit information.
Neurons
contains the cell nucleus and much of the chemical machinery common to most cells
Soma
are the parts of a neuron that are special-ized to receive information.
Dendrites
is a long, thin fiber that transmits signals away from the soma to other neurons or to muscles or glands.
Axon
The ______ is insulating material that encases some axons.
Mylein sheath
terminal buttons, which are small knobs that secrete
chemicals called
Neurotransmitters
A _______ is a junction where information is transmitted from one neuron to another
Synapse
are cells found throughout the nervous system that provide various types of support for neurons.
Glia Cells
The ________ of a neuron is its stable, negative charge when the cell is inactive.
The resting potential of a neuron is its stable, negative charge when the cell is inactive.
Responsible for Fight or Flight and prepares the body for action
Sympathetic Nervous division
Responsible for returning the body to its resting state
Parasympathetic nervous division
control key life-sustaining functions (e.g., breathing, heart beat) This is also the oldest part of the brain from an evolutionary standpoint Includes the Medulla and Pons
Brainstem
Lies above the pons and is Involved in processing of sensory information and early regulatory functions
Alertness
Sleep/wake
Temperature regulation
Considered part of brainstem
Midbrain
Involved in movement, motor learning, and sensory integration
Pattern recognition
Lies behind the brainstem
Cerebellum
Contains the cerebellum, medulla, pons
No Thalamus!
Hindbrain
