3. 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

6. 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

7.  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

Callosum
Thalamus
Hypothalamus

Brain Stem

9.  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

10.  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

12. 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)

13.  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
