The Cerebral LobesThe Cerebral LobesStructure Description

Frontal LobeThe largest cerebral lobe. Involved in movement, planning, and judgment. Contains the Motor Strip.

Parietal LobeAssociated with touch and sensation. Integrates sensory input. Contains Sensory-Motor Strip.

Temporal Lobe

Associated with hearing, auditory processing, memory, and speech.

Occipital Lobe

Associated with vision and visual processing.

Structure Description

Motor StripControls voluntary movements of the skeletal muscles. Located in the Frontal Lobe.

Sensory-Motor Strip

Receives sensory information from joints and tendons. Located in the Parietal Lobe.

Structure Function

Corpus Callosum

Band of axon fibers. Connects the two hemispheres of the brain for communication purposes.

Cerebral Cortex

1/8” thick, gray-colored outer layer of the cerebrum. Made up of billions of neurons. Associated with higher cognitive functions.

Forebrain and Hindbrain

Structure Description

CerebellumLocated at the base of the skull. Associated with movement, posture, and maintaining equilibrium.

Thalamus Processes all the senses except smell. Relays to the cortex.

Hypothalamus

Associated with hunger, thirst, sexual activity, and emotions. Maintains homeostasis. Influences the pituitary gland.

Forebrain And Hindbrain

Forebrain And Hindbrain

Structure Description

Pituitary Gland

The “master gland.” Secretes endorphins, the body’s natural painkiller.

MedullaControls breathing and heart rate. Controls sensory and motor pathways.

Amygala Associated with basic emotions, memory, and basic motivations.

Hippocampus

Associated with long-term memory.
