1
Question
Subarachnoid space
Answer
Space that contains cerebrospinal fluid - Between pia mater and dura mater
2
Question
Autonomic nervous system
Answer
Nerves for involuntary movement - Includes - Muscles - Glands sweating - Internal organs
3
Question
Cerebrum
Answer
Largest part of the brain - Performs - Thoughts - Consciousness - Actions
4
Question
Central nervous system CNS
Answer
Brain and spinal cord
5
Question
Dendrite
Answer
Microscopic branching fiber of a nerve cell - First to receive a nervous impulse
6
Question
Cerebellum
Answer
Posterior back part of the brain - Coordinated muscle movements and maintains balance
7
Question
Ependymal cell
Answer
Neuroglial cell - Lines membranes within brain and spinal cords - Helps form cerebrospinal fluid
8
Question
Cerebral cortex
Answer
Outer region of cerebrum - Contains sheets of nerves - On a diagram, is the upper part of the brain
9
Question
Cerebrospinal fluid
Answer
Circulates throughout brain and spinal cord - Provides brain protection, nourishment, and waste removal
10
Question
Dura mater
Answer
Thick, outermost layer of meninges
11
Question
Cranial nerves
Answer
12 pairs of nerves - Carries messages to and from the brain
12
Question
Ganglion
Answer
Collection of nerve cell bodies in PNS - Connects PNS to CNS
13
Question
Meninges
Answer
Membrane surrounding brain and spinal cord - Purpose is to protect CNS
14
Question
Glial cell
Answer
Supportive and connective type of nerve cell - Provides structural support - Regulates chemical and immune impulses - Doesnt carry nervous impulses
15
Question
Motor nerve
Answer
Carries messages away from brain and spinal cord - Efferent nerve
16
Question
Gyrus
Answer
Sheet of nerve cells - Makes the founded folds on brain surface - In Alzheimers disease, the gyrus shrinks up
17
Question
Axon
Answer
Microscopic fiber carrying signals along a nerve cell - Protected by Myelin sheath
18
Question
Myelin sheath
Answer
White, fatty tissue - Surrounds and insulates axons in nerve cells - Multiple sclerosis is marked by the degrading of the myelin sheath
19
Question
Hypothalamus
Answer
Controls sleep, appetite, body temperature, and pituitary gland secretions - Apart of temporal lobe
20
Question
Nerve
Answer
Macroscopic - Cord-like collection of fibers that carry electrical impulses - Has large variety of purposes
21
Question
Medulla oblongata
Answer
Just above spinal cord - Controls - Breathing - Heartbeat - Size of blood vessels
22
Question
Neuron
Answer
Nerve cell that carries impulses throughout the body
23
Question
Microglial cell
Answer
Phagocytis glial cell - Moves waste from Cranial Nervous System
24
Question
Peripheral nervous system PNS
Answer
Nerves outside of brain and spinal cord - Cranial and spinal nerves
25
Question
Neurotransmitter
Answer
Chemical messenger - Released at end of nerve cell - Examples - Dopamine - Serotonin - Epinephrine
26
Question
Pia mater
Answer
Thin, delicate inner membranes of meninges - Tiny film over brain - Purpose is to provide brain with blood and support
27
Question
Oligodendroglial cell
Answer
Glial cell that forms myelin sheath
28
Question
Plexus
Answer
Large, interlacing network of nerves - Branch out from spinal cord to PNS
29
Question
Parasympathetic nerves
Answer
Involuntary nerve that regulate normal body functions - Includes - Heart rate - Breathing - GI muscle movement
30
Question
Pons
Answer
Anterior to cerebellum, between medulla and midbrain - Relay center between brain and spinal cord
