Functional Areas of the Brain and Nervous System Overview ( 43-47pg)

These flashcards cover key functional areas of the brain, the nervous system, and the roles of cranial and spinal nerves.

What is the primary function of the Primary Motor Cortex?

The Primary Motor Cortex is responsible for the initiation of voluntary movements.

What is the role of Broca's area?

Broca's area is involved in speech production and language processing.

What is cerebral lateralization?

Cerebral lateralization refers to the specialization of the left and right hemispheres of the brain for different tasks.

What functions are associated with the left hemisphere of the brain?

The left hemisphere is primarily responsible for logical thinking, mathematics, language, reading, writing, and speech.

What functions are associated with the right hemisphere of the brain?

The right hemisphere is associated with creativity, art, music, recognizing faces, emotional expression, and spatial abilities.

What is the limbic system known for?

The limbic system controls emotions, motivation, learning, and memory, often referred to as the 'emotional brain'.

What is the main function of the amygdala in the limbic system?

The amygdala controls fear, anger, and emotional responses.

What is the difference between cranial nerves and spinal nerves?

Cranial nerves begin in the brain and control head and neck functions, while spinal nerves originate in the spinal cord and connect the body.

How many pairs of cranial nerves are there?

There are 12 pairs of cranial nerves.

What type of neurons do the dorsal ramus carry?

The dorsal ramus carries mixed (sensory and motor) neuron fibers.

What is a nerve plexus?

A nerve plexus is a network of merged spinal nerve branches that supplies nerves to specific body areas.

What is the main function of the phrenic nerve?

The phrenic nerve controls the diaphragm, the main muscle required for breathing.

What happens if the phrenic nerve is damaged?

Damage to the phrenic nerve can result in breathing difficulties or paralysis of the diaphragm.

What is the function of the olfactory nerve?

The olfactory nerve is responsible for the sense of smell.

What is the primary role of the optic nerve?

The optic nerve is responsible for vision.

What does the vagus nerve control?

The vagus nerve controls internal organs including the heart, lungs, and digestive tract.
