Question | Answer |
what is a Neurotransmitter chemical released at the ends of nerve cells? | Acetylcholine |
What carries messages toward the brain and spinal cord (sensory nerve)? | Afferent nerve |
What is the middle layer of the three membranes(meninges) that surround the brain and spinal cord? | Arachnoid Membrane |
Type of glial (neuroglial) cell that transports water and salts from capillaries? | Astrocyte |
Nerves that control involuntary body functions of muscles, glands, and internal organs. | Autonomic Nervous System |
Microscopic fiber that carries the nervous impulse along a nerve cell. | Axon |
Blood vessels (capillaries) that selectively let certain substances enter the brain tissue and keep other substances. | Blood-brain barrier |
Lower portion of the brain that connects the cerebrum with the spinal cord; includes the pons and medulla oblongata. | Brainstem |
Collection of spinal nerves below the end of the spinal cord. | Cauda Equina |
Part of a nerve cell that contains the nucleus | Cell Body |
Brain and spinal cord. | Central Nervous System (CNS) |
Posterior part of the brain that coordinates muscle movements and maintains balance. | Cerebellum |
Outer region of the cerebrum, containing sheets of nerves 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 |
Twelve pairs of nerves that carry messages to and from the brain with regard to the head and neck(except the vagus nerve). | Cranial Nerves |
Microscopic branching fiber of a nerve cell that is first part to receive the nervous impulse. | Dendrite |
Thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord; motor nerve. | Efferent Nerve |
Glial cell that lines membranes within the brain and spinal cord and helps form cerebrospinal fluid. | Ependymal Cell |
collection of nerve cell bodies in the peri pheral nervous system. | Ganglion(plural: ganglia) |
Supportive and connective nerve cell that does not carry nervous impulses. Examples are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. | Glial Cell(Neuroglial cell) |
