Chapter 9: Brain and Reflexes Review

Hypothalamus

Maintains homeostasis by regulating visceral activities

Thalamus

Receives all sensory impulses except for smell, sends them to cerebral cortex

Cerebral Cortex

Thin layer of gray matter on surface of cerebrum

Pons

Rounded bulge on underside of brainstem; regulates breathing

Brainstem

Most primitive functions in brain; includes the midbrain, pons, and medulla oblongata

Parietal Lobe

Understands speech

Convolutions/Gyri

Wrinkles and grooves on the surface of cerebrum

Sulci

Shallow groove on the surface cerebrum

Occipital Lobe

Analyze visual stimuli

Corpus Callosum

Connects cerebral hemispheres

Medulla Oblongata

Regulates cardiac, vasomotor and respiratory activities

Cerebellum

Maintains your coordination and balance

Cerebrum

Determines personality and intelligence

Midbrain

Part of brainstem between diencephalon and pons

Temporal Lobe

Stores memory of visual scenes, music, and complex patterns

Hippocampus

Processes memories

Transverse Fissure

Separates the occipital lobe and cerebellum

Cerebrospinal Fluid

Maintains ion balance in CNS

Diencephalon

Includes the thalamus, hypothalamus, and pineal gland

Pituitary Gland

Controls hormones

Spinal Cord

A portion of the CNS; a slender column of nervous tissue

Frontal Lobe

Responsible for thinking, planning, and problem solving

Ventricles

Produces cerebrospinal fluid

meninges

Protective membrane between bone and soft nervous tissue

Limbic System

Controls emotions and feelings
