What happens if nervous system is damaged?
You may experience the sudden onset of one or more symptoms, such as: Numbness, tingling, weakness, or inability to move a part or all of one side of the body (paralysis). Dimness, blurring, double vision, or loss of vision in one or both eyes. Loss of speech, trouble talking, or trouble understanding speech.
Why is an animal’s nervous system important?
The nervous system is the part of an animal’s body that coordinates its behavior and transmits signals between different body areas.
What is the function of nerve cell in animal?
Depending upon function, these cells can be divided into sensory neurons, interneurons, and motor neurons. These three types of nerve cells coordinate with each other to receive external stimuli and to transmit the impulse to muscles or glands of the body for an appropriate response to the stimulus.
How does the nervous system control behavior?
(1) Most behavior occurs in response to an external sensory stimulus of some kind; (2) sensory signals must be transduced into nerve signals; (3) nerve impulses travel along specific pathways to defined areas of the central nervous system; (4) nerve cells communicate with each other through specialized junctional zones …
How does the peripheral nervous system affect behavior?
The peripheral nervous system includes all of the neurons that sense and communicate data to the central nervous system. The peripheral nervous system can be further divided into the autonomic system, which regulates involuntary actions, and the somatic system, which controls voluntary actions.
What is the peripheral nervous system responsible for?
The peripheral nervous system (PNS) is the division of the nervous system containing all the nerves that lie outside of the central nervous system (CNS). The primary role of the PNS is to connect the CNS to the organs, limbs, and skin.
What is the importance of nervous system in exhibiting human behavior?
The central nervous system has a fundamental role in the control of behavior. It contains the brain and the spinal cord which are both encased in bone which shows their importance. Both the brain and spinal cord receive signals from the afferent neurons and send signals to muscles and glands through efferent neurons.
How does the nervous system affect our feelings?
The autonomic nervous system, together with the hypothalamus, regulates pulse, blood pressure, breathing, and arousal in response to emotional cues. Conversely, the parasympathetic nervous system functions when the body is relaxed or at rest and helps the body store energy for future use.
How does the brain affect our behavior?
A region of the old brain primarily responsible for regulating our perceptions of, and reactions to, aggression and fear. A brain structure that performs a variety of functions, including the regulation of hunger and sexual behavior, as well as linking the nervous system to the endocrine system via the pituitary gland.
How the nervous system affects the other organ system of animals?
The nervous system lets the animals to communicate with the outside environment, as well as with their own body. From outside, animals fetch information through the sense organs (eyes, taste buttons, olfactory epithelium, sensory nervous terminals of the integument sensible to touch and temperature).
What does the circulatory system and the nervous system have in common?
The bones of your skull and spine protect your brain and spinal cord, but your brain regulates the position of your bones by controlling your muscles. The circulatory system provides your brain with a constant supply of oxygen-rich blood while your brain regulates your heart rate and blood pressure.
