Part of hindbrain whose main functions include controlling finely coordinated movements and storing memories about movement, but may also be involved in impulse control, emotion, and language
Parts of the cerebral cortex not directly involved with either receiving specific sensory information or creating movement
autonomic nervous system
Carries messages back and forth between the CNS and the heart, lungs, and other organs and glands.
the chemicals which allow the transmission of signals from one neuron to the next across synapse
one of the four main regions/lobes in the brain
controlling visual perception and color recognition
Parasympathetic nervous system
part of nervous system that serves to slow the heart rate, increase the intestinal and gland activity, and relax the sphincter muscles.
A neuron fiber that receives signals from the axons of other neurons and carries those signals to the cell body
A network of cells and fibers threaded throughout the hindbrain and midbrain that alters the activity of the rest of the brain.
Somatic Nervous System
Part of the peripheral nervous system, transmits info from the senses to the CNS and carries signals from the CNS to the muscles that move the skeleton.
Receives signals from the somatic system in the periphery and relays them to the brain via fiber tracts within the spinal cord. The brain then relays signals to the muscles in your hands and arms.
largest, most highly developed part of the brain, composed of 2 hemispheres and 4 lobes, responsible for functions such as Thinking, Perceiving, Motor Function, Planning and Organization, Touch Sensation
the portion of the cerebral cortex roughly above the ears; includes the auditory areas, each of which receives auditory information primarily from the opposite ear
A fore-brain structure that relays signals from most sense organs to higher levels in the brain and plays an important role in processing and making sense out of this information
regulates growth; controls the thyroid, ovaries or testes, pancreas, and adrenal cortex; regulates water and salt metablolism
when a neuron is in polarization; more negative ions are inside the neuron cell membrane with a positive ions on the outside, causing a small electrical charge; release of this charge generates a neuron's impulse (signal/message)
Postsynaptic potential that either hyperpolarizes the neuron and makes it less likely that action potential will occur, or that hypopolarizes the neuron, making it more likely that action potential will occur
the extension of a neuron, ending in branching terminal fibers, through which messages pass to other neurons or to muscles or glands
the part of the brain that lies between the cerebellum and spinal cord that controls the body's involuntary actions
Central nervous system neurons that internally communicate and intervene between the sensory inputs and motor outputs
a system of functionally related neural structures in the brain that are involved in emotional behavior
An abrupt wave of electrochemical changes traveling down an axon when when a neuron becomes depolarized
A neurotransmitter used by neurons in the peripheral and central nervous systems in the control of functions ranging from muscle contraction and heart rate to digestion and memory
neurotransmitter used by cells in parts of brain involved in regulation of eating, sleeping, and mood
Efferent sensory neurons
carry nerve impulses away from the central nervous system to effectors such as muscles or glands
cells that form organs called glands and that communicate w/ one another by secreting chemicals called hormones
Controls language reception- a brain area involved in language comprehension and expression; usually in the left temporal lobe.
Cells in the nervous system that holds neurons together and helps them communicate with one another
