Broca's Area
(aka motor speech area)

*Functional area located on the frontal lobe, superior to the lateral fissure (above the "tip of the thumb")

*Only on the left hemisphere

*Controls or initiates speech

Primary Motor Cortex

*Functional area located on the precentral gyrus on the frontal lobe

*Controls skeletal muscle function

Primary Somatic Sensory Cortex

*Functional area located on the postcentral gyrus on the parietal lobe

*Receives sensory information

Somatic Sensory Association Area

*Functional area that covers of of the parietal lobe behind the primary somatic sensory cortex

*Makes sense of sensory input

Visual Cortex

*Functional area located on the occipital lobe

*Receives visual input

Wernicke's Area
(aka sensory speech area)

*Functional area located on the parietal lobe (above the "base of the thumb")

*Only on the left hemisphere

*Understands speech

A. Arachnoid Mater

*Above is subdural space and dura mater

*Below is subarachnoid space (filled with cerebrospinal fluid) and pia mater

A. Brainstem

*Consists of the midbrain, pons and medulla oblongata

A. Broca's Area
(motor speech)

*Functional area located on the frontal lobe, superior to the lateral fissure (above the "tip of the thumb")

*Only on the left hemisphere

*Controls or initiates speech

A. Frontal Lobe
B. Central Sulcus
C. Parietal Lobe

A. Cerebellum

*Involved with balance and coordination

A. Cerebellum

*Involved with balance and coordination

A. Cerebrum

*Controls voluntary motor movement
*Received and interprets sensory inputs
*Involved in cognitive and emotional processing

A. Dura Mater

*Above is epidural space and skull
*Below is subdural space and arachnoid mater

A. Hypothalamus

*Anterior and inferior to the thalamus

*Regulates thirst, hunger and body temperature

*Regualtes feelings of rage and aggression, pain, and pressure

*Controls the pituitary gland

A. Frontal Lobe
B. Parietal Lobe
C. Temporal Lobe
D. Lateral Fissure (separates temporal lobe from frontal and parietal lobes)

A. Longitudianl Fissue

*Divides the brain into right and left hemispheres

A. Medulla Oblongata

*Most inferior portion of the brainstem
*Regulates heart rate, blood pressure, breathing, coughing, sneezing, vomiting and hiccups. (maintains homeostatic functions)

A. Midbrain

*Most superior portion of the brainstem
*Relays sensory and motor impulses, involved in hearing and visual reflexes

A. Parieto-occipital Sulcus

* Separates the praietal from the occipital lobe

B. Occipital lobe

A. Cerebrum
-Receives and interprets sensory inputs
-Controls voluntary motor movements
-Involved in cognitive and emotional processing (thinking(

B. Brainstem
-Consists of the midbrain, pons and medulla oblongata

C. Cerebellum
-Regulates coordinated skeletal muscle movements, posture and balance

A. Pia Mater

*Covers every surgace of the brain
*Directly attached to brain surface - cannot be removed without destroying the brain

A. Pineal Gland

*Located within the epithalamus
*Part of the diencephalon
*Posterior to the thalamus

*Produces melatonin
*May contribute to setting the sleep/wake cycle

A. Pons

*Middle section of the brainstem

*Relays information from the cerebrum to the cerebellum

A. Postcentral Gyrus

*Located directly posterior to the central sulcus

A. Precentral Gyrus

*Located directly anterior to the central sulcus

A. Somatic Sensory Association Area

*Located on the parietal lobe (everything behind the postcentral gyros)

*Involved with the ability to recognize an object by touch

A. Thalamus

*Directly superior to the midbrain

*Relay station for most sensory impulses to the cerebral cortex

A. Third Ventricle
-Below lateral ventricles
-Drains into fourth ventricle
-Runs through the center of the thalamus

B. Lateral Ventricles
-One in each hemisphere
-Drains into the third ventricle

C. Fourth Ventricle
-Located directly behind the brainstem and in front of cerebellum

A. Lateral Ventricles

(sensory speech)

*Located on the parietal lobe (above the "base of the thumb")

*Understands speech
