Hemispheres of the Brain
The Brain and the Spinal Cord
Spinal Cord Part of the central
nervous system.
Bundle of nerves that passes through the bones of the vertebrae down the back.
Sends sensations to the brain from the body, and returns motor commands to the various parts of the body.
primary role in reflexes and in the autonomic nervous system
BRAIN
SPINALCORD
Frontal Lobe
Motor Cortex
Sensory Cortex
Parietal Lobe
Wernicke’s Area
Occipital Lobe

Broca’s Area
Lobes of the Brain
Frontal Lobe
Temporal Lobe
Parietal Lobe
Occipital Lobe
Lobes of the Brain Description
Frontal Lobe Portion of cerebral cortex lying just behind the forehead
Involved in speaking and muscle movements and in making plans and judgments
Parietal Lobe Portion of cerebral cortex lying at the top of the head and towards the rear
Receives sensory input for touch and body positions
Its association areas work with the sensory signals or accurate perception
Temporal Lobe Portion of cerebral cortex lying roughly above the ears; includes auditory areas,
each receiving info primarily from opposite ear; controls hearing
Occipital Lobe Portion of cerebral cortex lying at the back of the head; Includes areas that
receive info from visual fields
Controls vision; contains visual cortex
Motor cortex an area at the rear of the frontal lobes that controls voluntary movements
Sensory Cortex area at the front of the parietal lobes that registers and processes body touch
and movement sensations
Visual cortex Area in the occipital lobe that receives input from eyes
Broca’s Area one of the main areas of the cerebral cortex responsible for speech production
Wernicke’s Area responsible for the comprehension of speech
Brain Stem
Pituitary Gland
Hypothalamus
Thalamus
Corpus Callosum
Cerebellum
Cerebral Cortex
Thalamus: Directs messages to sensory receiving areas in cortex and transmits replies to
cerebellum and medulla
Structure through which all sensory info (except smell) must pass through to get to cerebral cortex
Brainstem responsible for automatic survival functions
Cerebellum Helps coordinate movement; tells brain what to expect from body’s own
movement
Functions include processing sensory input and coordinating movement output and balance
Enables 1 type of nonverbal learning and memory; helps us judge time, modulate our emotions, and discriminate sounds and textures
Hypothalamus Directs several maintenance activities (i.e. sexual behavior, eating, drinking,
body temperature), helps govern endocrine system via pituitary gland, and is linked to emotion and reward
Pituitary Gland "Master Gland" because it secretes hormones and directs other organs and
endocrine glands, such as the adrenal glands, to suppress or induce hormone production.
Cerebral Cortex intricate fabric of interconnected neural cells covering the cerebral hemispheres
Body’s ultimate control and information processing center
Deeply convoluted over surface (“bark” of cerebrum most strongly linked to intelligence)
Corpus Callosum Divides the cerebrum into left and right hemispheres
Connects the left and right sides of the brain allowing for communication between both hemispheres
Transfers motor, sensory, and cognitive information between the brain hemispheres
Thalamus
Reticular Formation
Pons
Medulla
BRAINSTEM
Cerebellum
Parts of the Brainstem
Reticular Formation plays a role in regulation of sleep, arousal, and dreaming
Pons part of brainstem that acts as the “bridge” between brain stem and cerebellum
involved with sleep, arousal, and coordination of movements
Medulla base of brainstem, attached to spinal cord
controls unconscious but vital functions (i.e. breathing and heartbeat)
Amygdala Hippocampus
Amygdala 2 lima bean sized neural
clusters in limbic system linked to emotion (i.e. fear, aggression) that works with frontal lobe to regulate emotional responses
Hippocampus Processes memories
