Structure of the brain that deals with thinking, personality, sensations, movements, memory: _____________
Cerebrum
Structure of the brain that is the relay station (“triage center”) for sensory impulses; control of awareness and consciousness
Thalamus
Structure of the brain that controls body temperature, sleep, appetite, emotions; control of the pituitary gland: __________
Hypothalamus
Structure of the brain that deals with coordination of voluntary movements and balance
Cerebellum
Structure of the brain that functions as connection of nerve and nerve fiber pathways, including those to the eyes and face
Pons and midbrain
Structure of the brain that’s function is: nerve fibers cross over, left to right and right to left; contains centers to regulate heart, blood vessels, and respiratory system
Medulla oblongata
Collection is spinal nurse below the end of the spinal cord
Cauda equina
Neurotransmitter chemical released at the ends of nerve cells
Acetylcholine
Carries message toward the brain and spinal cord (sensory nerve).
Afferent nerve
Middle layer of the three membranes (meninges) that surround the brain and spinal cord.
Arachnoid membrane
Type of glial (neruoglial) cell that transports water and salts from capillaries in the nervous system
Astrocyte
Nerves that control, involuntary body functions of muscles, glands, and internal organs
Autonomic nervous system
Microscopic fiber that is part of a neuron and carries nervous impulse along the nerve cell
Axon
Protective separation between the blood and brain cells. This makes it difficult for substances (such as anti-cancer drugs) to penetrate capillary walls and enter the brain.
Blood-brain barrier
Posterior portion of the brain that connects the cerebrum with the spinal cord; includes the midbrain ponds and medulla oblongata
Brainstem
Part of a nurse cell that contains the nucleus
Cell body
Central Nervous System (CNS)
Brain and spinal cord
Posterior part of the brain that coordinates muscle movements and maintains balance
Cerebellum
Outer region of the cerebrum, containing sheets of nerve cells; gray matter of the brain
Cerebral cortex
Circulates throughout the brain and spinal cord
Cerebrospinal fluid (CSF)
Largest part of the brain; responsible for voluntary muscular activity, vision, speech, taste, hearing, thought, and memory
Cerebrum
Nurse key messages to inform the branch to all parts of the head and neck and also (in the case of the vagus nerve) to other parts of the body. There are 12 pairs.
Cranial nerves
Microscopic, branching, fiber of a nerve cell (neuron) that is the first part to receive the nervous impulse
Dendrite
Thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord
Dura mater
Carrie’s messages away from the brain and spinal cord; motor nerve
Efferent nerve
Glial cell that lines membranes within the brain and spinal cord, helps form cerebrospinal fluid
Ependymal cell
Collection of nerve cell bodies in the peripheral nervous system
Ganglion (plural: ganglia)
Supportive and connective nerve cell that does not carry nervous impulses.
Glial cell (neuroglial cell)
- astrocytes
- microglial cells
- ependymal cells
- oligodendrocytes
Sheet of nerve cells that produces round range on the surface of the cerebral cortex court; convolution
Gurus (plural: gyri)
Portion of the brain beneath the thalamus; control, sleep, appetite, body temperature, and secretions from the pituitary gland
Hypothalamus
Part of the brain, just above the spinal cord; controls, breathing, heart rate, and the size of blood vessels; nerve fibers cross over here
Medulla oblongata
Three protective membranes that surround the brain and spinal cord
Meninges
Phagocytic glial cell that removes waste products from the central nervous system
Microglial cell
Uppermost portion of the brainstem
Midbrain
Carrie’s message is away from the brain and spinal cord to muscles and organs that; efferent nerve
Motor nerve
