Unit 2.1 Nervous System Exam Review

This structure of the nervous system consists of two hemispheres, left and right, and is responsible for the integration of sensory and neural functions and the initiation and coordination of voluntary activity in the body.

• Cerebrum

• Cerebellum

• Spinal Cord

• Peripheral Nervous System

This structure of the nervous system is at the back of the skull and functions to coordinate and regulate involuntary muscular activity.

• Cerebrum

• Cerebellum

• Spinal Cord

• Peripheral Nerves

A groove or furrow on the surface of the brain.

• Cerebellum

• Gyrus

• Sulcus

• Lobe

A ridge or fold between two clefts on the cerebral surface in the brain.

• Cerebellum

• Gyrus

• Sulcus

• Lobe

Any of the cells that hold nerve cells in place and help them work appropriately.  There are many types of this cell.

• Sensory neuron

• Motor neuron

• Interneuron

• Glial Cells

Nerve cells that are activated by inputs or that receive outside stimuli and then sends of signals to the rest of the nervous system.

• Sensory neurons

• Interneurons

• Motor neurons

• Glial cells

Nerve cells that pass impulses from the brain or spinal cord to a muscle or gland.

• Sensory neurons

• Interneurons

• Motor neurons

• GLial cells

A nerve cell which transmits impulses between other neurons.

• Sensory neurons

• Motor neurons

• Interneurons

• Glial cells

The part of the neuron that insulates the axon and increases the speed of the neural message within the neuron.
