Key Concepts & Comparisons

Retake anatomy brain section

Sensory Cortex vs Motor Cortex

Sensory cortex receives touch and body sensations; motor cortex controls voluntary movement. Sensory is in the parietal lobe, motor is in the frontal lobe.

Vision Processing

Occipital lobe.

Hearing Processing

Temporal lobe.

Smell Processing

Temporal lobe.

Taste Processing

Parietal lobe.

Touch Processing

Parietal lobe.

Gyri

Raised folds of the brain that increase surface area.

Sulci

Shallow grooves between gyri.

Fissures

Deep grooves that separate major brain regions.

Central Nervous System (CNS)

Includes the brain and spinal cord; processes information.

Peripheral Nervous System (PNS)

All nerves outside the CNS; carries information to and from the CNS.

Sympathetic Nervous System

Activates the body during stress; “fight or flight.”

Parasympathetic Nervous System

Calms the body and conserves energy; “rest and digest.”
