Cerebrum
Outer part of the brain- Divided into two hemispheres-each hemisphere divided into lobes
Occipital Lobe
Processes, integrates, and
... [Show More] interprets vision.
-Primary Visual Cortex
-Primary area/site for vision;
-recognizes shape, color, light, motions, and dimensions. -The Visual Association Area
-interprets info from the primary visual cortex

Frontal lobe
§ The most developmental part of the brain
§ Memory, Emotions, Decision Making and Reasoning, Personality
§ Primary Motor Cortex
□ Body movement
§ Broca's Area
□ speech and facial movement
§ Orbital frontal Cortex
□ Behavior
§ Olfactory Bulb
□ Sense of smell
Temporal Lobe
§ Hearing, Organization/Comprehension of language/ information Retrieval (Memory and memory formation)
§ Primary Auditory Cortex
□ Process the hearing
§ Primary Olfactory Cortex
□ Interprets the sense of smell once it reaches the cortex via the olfactory bulbs.
§ Wernicke's Area (left temporal lobe)
□ Language Comprehension
Parietal Lobe
§ Integration of sensory information
§ Sense of boundary, sense of awareness of spatial experience, sense of perception
§ Primary Somatosensory Cortex/ Postcentral Gyrus
□ Sense of position of body parts, and location in relation to each other
§ Somatosensory Association Cortex
□ Integration and interpretation of the senses in relation to body position and orientation space
§ Primary Gustatory Cortex
□ Interpretations Sense of taste and smell
Midsagittal Sections
divides the brain vertically down the central fissure between the two hemispheres-divides through the corpus callosum, which connects the two hemispheres.
Spinal Cord
○ Messages between nerves and brain
□ Ascending-senses go to the brain
□ Descending -brain sends messages to motor cortex
○ Rhythmic movements
○ Reflexes
Medulla Oblongata
○ In lower half of brainstem,
○ Controls heart beat, respiration and circulation
functions respiratory, cardiovascular, control reflex centers for vomiting, coughing and sneezing
Pons
○ Located on the brainstem
○ Provides inputs to other structures in the brainstem
○ Regulation of motor messages ==> Cerebellum
Nuclei regulate respiration
Cerebellum
○ Balance and posture
○ Rapid sequence movements
Thalamus
Channels sensory information and directs to appropriate area of cerebral cortex
Reticular Formations
Basic functions; alertness, sleeping patterns, wakefulness
Midbrain
○ initial orientation to sound, vision, sight, light
§ Superior colliculus - Blind sight -sense something that's happening; eyes
Inferior colliculus -orientation to loud noises
Corpus Callosum
connects the two hemispheres
Hypothalamus
Regulates with body temp and blood sugar's level (homeostasis)
Limbic system
forms the inner border of the cortex. Functions: emotion formation, processing, leaning and memory.
Amygdala
Primary role in memory of emotional reactions.
Pineal Gland
§ Sleep/wakefulness cycle
§ Produces melatonin-hormones to help sleep
Master gland: secretes long and short term hormones
Pituitary gland
Releases hormones related to endocrine system
Central Nervous system
Brain and Spinal Cord
Peripheral Nervous system
Somatic Nervous system- the actions we do ourselves
Autonomic Nervous System-the actions we do naturally
-Sympathetic Division (energy consuming)
-Parasympathetic Division (rest and digest)
-Enteric Division (rest and digest) [Show Less]
