19 Terms

1

Cerebral Cortex

The superficial gray matter of the brain accounting for 40% of its mass; enables sensation, communication, memory, understanding, and voluntary movements.

New cards
2

Homunculus

Topographical representation of the motor and sensory cortexes indicating how different body regions correlate to areas in the brain.

New cards
3

Gray Matter

Contains neuron cell bodies and short nonmyelinated neurons; located at the central part of the spinal cord and within the brain.

New cards
4

White Matter

Mostly myelinated axons found outside the gray matter; responsible for communication between different parts of the CNS.

New cards
5

Lateralization

The idea that each hemisphere of the brain has abilities not shared with its partner.

New cards
6

Wernicke's Area

Area of the brain involved in language comprehension and word analysis, typically located in the left hemisphere.

New cards
7

Broca's Area

Motor speech area located in the frontal lobe that directs the muscles of the tongue and is active during speech preparation.

New cards
8

Thalamus

Part of the diencephalon, it relays all afferent impulses from senses and plays a key role in sensation, motor activities, and memory.

New cards
9

Hypothalamus

A central part of the diencephalon that regulates various body functions including temperature, hunger, and the sleep cycle.

New cards
10

Cerebellum

Area of the brain responsible for precise timing and patterns of muscle contractions, contributing to smooth coordinated movements.

New cards
11

Cerebrospinal Fluid (CSF)

A watery solution similar to blood plasma that nourishes the brain, protects it from trauma, and provides a cushion.

New cards
12

Meninges

Three connective tissue membranes protecting the CNS: dura mater, arachnoid mater, and pia mater.

New cards
13

Central Canal

A hollow tube in the spinal cord that contains cerebrospinal fluid.

New cards
14

Dura Mater

The tough, outer layer of the meninges that surrounds the brain and spinal cord.

New cards
15

Arachnoid Mater

The middle layer of the meninges that contains a wide subarachnoid space filled with cerebrospinal fluid.

New cards
16

Pia Mater

The delicate inner layer of the meninges that clings tightly to the surface of the brain.

New cards
17

Cerebral White Matter

Consists of myelinated fibers and is responsible for communication between the cerebral cortex and lower CNS centers.

New cards
18

Cerebral Hemispheres

The two halves of the cerebrum which control different functions and are involved in lateralization of brain function.

New cards
19

Cerebral Aqueduct

A hollow tube connecting the third and fourth ventricles, located in the midbrain.
