Nervous System

It is involved in receiving information about the environment around us and generating responses to that information and coordinating the system

The main processing center for the entire nervous system. It consists two main components, the brain and spinal cord

An organ that located within the skull that function as organizer and distributor of information for the body

Serves as a channel for signals between the brain and the rest of the body, and controls simple muscolosketal reflexes without input to from the brain

It connects the central nervous system to the organs and limbs and it has two main division, the spinal nerves and cranial nerves

The nerves that carry motor and sensory signals between the spinal cord and the body

The nerve fibers that carry information into and out of the brain stem

Is is activated when the body is in a dynamic role or stress

Maintains body functions and restores the body to normal or relaxed mode

Major functions of the Nervous System

Refers to receiving information (stimuli/stimulus) about the environment, either what is happening outside or inside the body

Refers to anything that causes a response

Received by sensory structures are communicated to the nervous system where that information is processed

The nervous system produces a response in effector organs (such as muscles or glands) due the sensory stimuli

It is the major part of the brain that ontrols the activities, thoughts, and five senses

Responsible for cognitive functions and movements

Responsible for processing touch, pain, temperature and movement

Responsible for vision

Responsible for speech, hearing and memory

It controls posture, balance and the fine muscle movements

It controls bodily functions like breathing, circulation and sleep, it is located in the bottom part of the brain and connects the cerebrum to the spinal cord

Specialized cells that transmit messages to and from the brain and spinal cord thought-out the body

Receives the signals from other neurons or from the body and pass those messages along the cell body

Maintains structure of the neuron and provides energy or electrical signals
