The nervous system's ultimate function is to interpret and respond to sensory signals from the environment.
The nervous system consists of two main categories:
1. Peripheral Nervous System (PNS): receives sensory stimuli, passes stimulus information to CNS in the form of an electrical action potential.
2. Central Nervous System (CNS): consists of brain and spinal cord; interprets signals coming from sensory stimuli in the periphery and decides appropriate response to initiate
- Afferent neurons transmit sensory signals from the PNS to the CNS
- Efferent neurons transmit response signals to targets in the body to respond accordingly to initial sensory stimulus.
The nervous system.
The branch of the life sciences which deals with the structure and function of the nervous system is called neuroscience.
Myelin is found in the nervous system and is produced by cells called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system. Its function is to insulate and protect neurons, as well as speed up the transmission of electrical impulses along nerve cells.
The peripheral nervous system contains mixed nerves (both sensory and motor) that the musculoskeletal needs to function.
The two branches of the autonomic nervous system are the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is responsible for the "fight or flight" response, increasing heart rate, dilating pupils, and releasing adrenaline. The parasympathetic nervous system is responsible for the "rest and digest" response, slowing heart rate, constricting pupils, and aiding in digestion.
1. What are the two kinds of installation of an operating system? Explain Briefly.
utility software commonly supplied with an operating system and briefly explain their function.
there are nervous
One function of the nervous system is to maintain the entire body.
The nervous system functions do not form thoughts but it could contribute to them. Arousal, which is a nervous system function, could lead to desire.
Yes it is true that excretion is one function of the digestive system. The nervous system is made up of the peripheral nervous system and central nervous system.
the main function of the peripheral is to connect the centeral nervous system with limbs and organs.
gago
The parasympathetic nervous system stinulates erection and the sympathetic nervous system stimulates ejaculation.
The nervous system controls breathing rate.
It can function with the skeletal system and the nervous system.
interneurons carry out the integrative function of the nervous system.
