Aging produces various structural and functional changes in the nervous system, including: reduction in brain size and weight, reduction in number of neurons, decrease in blood flow to brain, changes in synaptic organization of the brain, and intercellular and extracellular changes in CNS neurons.

Which human body system is a communication and control system?
The nervous system is the communication and control system of the human body. It consists of the brain, spinal cord, and nerves that transmit signals throughout the body to coordinate various functions and responses.
Nevrous system controlling heart pupils of the eye etc?
The nervous system controls the heartbeat by sending electrical signals through the heart's specialized cells. Pupil size is regulated by the autonomic nervous system, with the sympathetic system dilating the pupils and the parasympathetic system constricting them. Overall, the nervous system plays a crucial role in regulating various bodily functions, including heart rate and pupil size, to maintain homeostasis.
What is a nerve system?
The nervous system is a network of specialized cells that communicate information about an animal's surroundings and itself. It processes this information and causes reactions in other parts of the body. It is composed of neurons and other specialized cells called glia, that aid in the function of the neurons. The nervous system is divided broadly into two categories: the peripheral nervous system and the central nervous system. Neurons generate and conduct impulses between and within the two systems. The peripheral nervous system is composed of sensory neurons and the neurons that connect them to the nerve cord, spinal cord and brain, which make up the central nervous system. In response to stimuli, sensory neurons generate and propagate signals to the central nervous system which then processes and conducts signals back to the muscles and glands. The neurons of the nervous systems of animals are interconnected in complex arrangements and use electrochemical signals and neurotransmitters to transmit impulses from one neuron to the next. The interaction of the different neurons form neural circuits that regulate an organism's perception of the world and what is going on with its body, thus regulating its behavior. Nervous systems are found in many multicellular animals but differ greatly in complexity between species.
Does your age affect your reflexes?
Yes, age can affect reflexes. As we age, our reflexes tend to slow down due to changes in our nervous system and muscle strength. However, regular physical activity and exercise can help maintain and improve reflexes as we get older.
What two body system work together to coordinate and control all other body systems?
The nervous system and the endocrine system work together to coordinate and control all other body systems. The nervous system uses electrical signals to communicate quickly, while the endocrine system uses hormones to communicate more slowly but with longer-lasting effects. Together, these two systems help regulate functions such as metabolism, growth, and response to stress.
When you step on a needle what happens to nervous system?
the nervous system reacts
What happens to your nervous system when you break your leg?
your nervous system tells your brain that it hurts and you fell pain.
What weakens the nervous system?
The head injury and age are two things that weaken the nervous system. Hard and manual jobs also weaken the nervous system.
What happens in your nervous system when you eat?
Your memories dear
What happens within the body's nervous system during exercise?
The nervous system receives information and by the sensory nerves it transports to the brain what you learnt.
What happens when you sever the central nervous system?
You will either be paralysed or dead!
What happens when the sympathetic division of the nervous system is stimulated?
it stimulates the gastrointestinal activity
What happens in the nervous system?
The nervous system controls and coordinates all body functions by sending and receiving electrical signals through neurons. It is divided into the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves outside the brain and spinal cord). The nervous system allows for sensory perception, voluntary movement, and involuntary processes like heart rate and digestion.
What organ system does the brain belong too?
The nervous system The central nervous system
Does the central nervous system consist of the somatic nervous system?
No. Nervous System is comprised of the Central Nervous System (CNS) and the Peripheral Nervous System (PNS) The PNS is comprised of the Somatic Nervous System and the Autonomic Nervous System The Autonomic Nervous System is comprised of the Sympathetic Nervous System, the Parasympathetic Nervous System and the Enteric Nervous System
What happens to partly digested protein when it passes into the small intestines?
It can cause problems in the nervous system and the Cardiovascular system.
In the central nervous system the what communicates with and coordinates what happens in other parts of the brain?
Cerebrum
