Gross Anatomy Of The Brain And Cranial Nerves

Front 1

Name the 3 major regions of the brain

Back 1

1. forebrain

2. midbrain

3. hindbrain

Front 2

What brain structures form the forebrain?

Back 2

the cerebrum (the cerebral hempispheres: the cortex, white matter, and basal nuclei) and the diencephalon (the thalamus, the hypothalamus, and the epithalamus)

(lateral ventricles)

(third ventricles)

Front 3

What brain structures form the midbrain?

Back 3

the brain stem: midbrain

(cerebral aqueduct)

Front 4

What brain structures form the midbrain?

Back 4

brain stem: pons

cerebellum

brain stem: medulla oblongata

(fourth ventricle)

Front 5

The Primary Somatosensory Cortex

Back 5

Location: the postcentral gyrus of the parietal lobe

Function: receives impulses from the body's sensory receptors (such as those for pressure, pain, and temperature)

Front 6

Somatosensory Association Cortex

Back 6

Location: posterior to the primary somatic sensory cortex on the parietal lobe

Function: allows you to become aware of pain, coldness, a light touch, and the like

Front 7

Primary Motor Cortex

Back 7

Location: precentral gyrus of the frontal lobe

Function: responsible for conscious or voluntary movement of the skeletal muscles

Front 8

Broca's Area

Back 8

Location: found at the base of the precentral gyrus just above the lateral sulcus

Function: controls muscles responsible for the production of speech (works with the primary motor cortex). articulation center.

Front 9

Wernicke's Area

Back 9

Location: on the left parietal lobe, posterior to the lateral fissure (located on left side only)

Function: an area in which unfamiliar words are sounded out. speech center.

Front 10

Frontal Lobe

Back 10

associated with reasoning, planning, parts of speech, movement, emotions, and problem solving

Front 11

Parietal Lobe

Back 11

associated with movement, orientation, recognition, perception of stimuli

Front 12

Occipital Lobe

Back 12

associated with visual processing

Front 13

Temporal Lobe

Back 13

associated with perception and recognition of auditory stimuli, memory, and speech

Front 14

Central Sulcus

Back 14

Separates the Frontal Lobe from the Parietal Lobe

Front 15

Lateral Sulcus

Back 15

Separates the Temporal Lobe from the Parietal Lobe

Front 16

Parieto-occipital Sulcus

Back 16

on the medial surface of each hemisphere divides the occipital lobe from the parietal lobe

Front 17

Precentral Gyrus

Back 17

It is the location of the motor strip that controls voluntary movements of the contralateral side of the body

Front 18

Postcentral Gyrus

Back 18

It is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch

Front 19

Cerebellum

Back 19

is a region of the brain that plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language, and in regulating fear and pleasure responses, but its movement-related functions are the most solidly established

Front 20

Pons

Back 20

consists primarily of motor and sensory fiber tracts connecting the brain with lower CNS centers

Front 21

Medulla Oblongata

Back 21

this structure is the caudal-most part of the brain stem, between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate

Front 22

Longitudinal Fissure

Back 22

Separates the Left Hemisphere from the Right Hemisphere

Front 23

Cerebral Cortex

Back 23

the outer layer of the cerebrum (the cerebral cortex ), composed of folded gray matter and playing an important role in consciousness
