Structures and Functions of the Nervous System. The nervous system controls body activities and perceives and reacts to internal and external stimuli.
The nervous system controls body activities and perceives and reacts to internal and external stimuli.
The nervous system is composed of two main divisions, the central nervous system and the peripheral nervous system.
The brain is the main site of nervous control and is divided into three main parts: the medulla oblongata, the cerebellum, and the cerebrum.
The spinal cord is a continuation of the medulla oblongata and is located in the center of the vertebral column.
The medulla oblongata or brain stem controls reflex actions such as breathing, swallowing, coughing, and blinking of eyelids.
The cerebellum is the part of the brain that regulates balance and movement through impulses received from the eyes, ears, muscles, joints, and skin.
The cerebrum is the largest and most active part of the brain. It is the decision making center of the brain and controls memory, sight, hearing, smelling, and voluntary muscle contractions.
The peripheral nervous system includes all nerve structures beyond the brain and spinal cord.
The peripheral nervous system includes 12 cranial nerves, spinal nerves, and the autonomic nervous system.
As a group of 2-3 students make an infomercial about the structures and functions of the nervous system.
