Spe sci nervous system

plays a key role in the integration and control of the various life processes of the human body.

• Nervous system

• Respiratory system

You can consider the nervous system to be a control network where messages are exchanged and interpreted in the form of electrical signals called

 

• Impulses

• Pluses

•  monitors internal & external environment through the presence of receptors

•  

• Sensory

• Motor

• interpretation of sensory information (information processing); complex (higher-order) functions

•  

• Integration

• Motor

•  

  response to information processed through stimulation of effectors

  •  muscle contraction

  •  glandular secretion

• Motor

• Sensory

• represents the largest part of the nervous system. It coordinates all of the body’s activities and mostly consists of interneurons. 

• This conceived as a system devoted to information processing . 

• Functions of this include sending messages, processing information, storing information, and analyzing responses.

• Central nervous system

• Peripheral nervous system

• is a vast network of spinal and cranial nerves that are linked to the brain and the spinal cord. It contains sensory receptors which help in processing changes in the internal and external environment. This information is sent to the CNS

• Peripheral nervous system

• Central nervous system

• has involuntary control of internal organs, blood vessels, smooth and cardiac muscles. . 

• automatic

• somatic

• has voluntary control of skin, bones, joints, and skeletal muscle.

• Automatic

• Somatic

•  It is the part of the autonomic nervous system located near the thoracic and lumbar regions in the spinal cord. function is to stimulate the body’s fight-or-flight response. It does this by regulating the heart rate, rate of respiration, pupillary response, and more.

• Sympathetic autonomic nervous system

• Parasympathetic autonomic nervous system
