Brain Parts and Functions

Parietal Lobe

Parietal Lobe

Sensory (temperature, touch, pain, pressure)

Parieto-occiptal Fissure

Cerebellum

Cerebellum

Balance and coordination, fine tuning muscle movement

Occipital Lobe

Occipital Lobe

responsible for vision

Central Fissure

Divides the frontal and parietal lobes

Sensory Strip

(also called postcentral gyrus or primary sensory cortex)

Motor Strip

(also called precentral gyrus or primary motor cortex)

Frontal Lobe

Frontal Lobe

movement, abstract thinking, planning, memory, behavior, personality, creativity, speech, and judgement

Lateral Fissure

separates temporal and parietal lobes

Temporal Lobe

Temporal Lobe

hearing, memory, emotions

Pons

A brain structure that relays information from the cerebellum to the rest of the brain, plays a role in breathing

Pons

Medulla Oblongata

Medulla Oblongata

Part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.

Cerebellum

Medulla Oblongata

Pons

Pituitary Gland

Pituitary Gland

Under the influence of the hypothalamus, releases hormones to control growth.

Hypothalamus

Hypothalamus

A neural structure lying below the thalamus; it directs several maintenance activities (eating, drinking, body temperature), governs the pituitary gland

Thalamus

Thalamus

the brain's sensory switchboard, directs messages to the sensory receiving areas in the cerebrum, associates feelings of pleasantness or unpleasantness with sensations.

Corpus Callosum

large band of fibers connecting the two brain hemispheres and carrying messages between them

Corpus Callosum

Dura Mater

Outer layer

Arachnoid Mater

Middle layer, web-like

Subarachnoid Space (CSF)

Lies between the arachnoid mater and the pia mater

Pia Mater

Inner layer

Cerebrum

Largest part of the brain associate with higher mental functions.

Diencephalon

Processes sensory input

Cerebellum

Skeletal muscle coordination, equilibrium and balance

Brain Stem

Pons, midbrain & medulla oblongata - coordinates and regulates visceral (organ) activities

Frontal Lobe

Motor decisions, personality traits, abstract reasoning and skeletal muscle control

Parietal Lobe

Sensory (temperature, touch, pain, pressure)

Temporal Lobe

Auditory, memory

Occipital Lobe

Vision

Cerebral Cortex

Thin gray (unmyelinated) layer on the outside of the cerebrum

Longitudinal Fissure

Divides the cerebral hemispheres

Corpus Callosum

Connects the cerebral hemispheres

Central Fissure

Divides the frontal and parietal lobes

Parieto-occipital Fissure

Divides the occipital and parietal lobes

Broca's Area

Responsible for speech production

Wernicke's area

language comprehension

Thalamus

Relay station for sensory impulses, produces emotions of pleasantness or unpleasantness with sensations

Hypothalamus

Homeostasis controller! Controls appetite, body temperature, sex drive, water balance, metabolism and pleasure

Pineal Gland

Melatonin secretion (body's clock)

Pituitary Gland

Secretes hormones under control of hypothalamus

Midbrain

Relay for visual and auditory impulse; allows you to turn your head towards a sound or sight

Pons

Regulates respiratory rhythm (breathing)

Medulla Oblongata

Controls vital functions - BP, heart rate, coughing, breathing, sneezing, swallowing, vomiting

Gyri

Ridges / folds

Sulci

Shallow groove

Fissure

Deep groove

Motor decisions, personality traits, abstract reasoning and skeletal muscle control

Divides the frontal and parietal lobes

Sensory (temperature, touch, pain, pressure)

Divides the occipital and parietal lobes

Skeletal muscle coordination, equilibrium and balance

Vision

Auditory, Memory

Regulates respiratory rhythm (breathing)

Controls vital functions - BP, heart rate, coughing, breathing, sneezing, swallowing, vomiting
