...nervous system, sympathetic division b. somatic nervous system, autonomic nervous system c. thalamus, hypothalamus d. peripheral nervous system, motor 10) Do the CNS and the PNS function independently of each other? Explain. 11) What kind of information is carried in the ventral roots of...The nervous system is a network of nerve cells and, in most animals, a brain. Some of these neurons carry information from sensory organs that detect touch, light, or other The presence of a brain allows the organism to receive a wide array of information from the environment, analyze it...Nervous system. Controls and coordinates functions through out the body and responds to internal and external stimuli. This division of the nervous system relays information form the brain and spinal cord to the organs and other glands as well as receives information from the environment.• Information from the receptor cells is transmitted by nerve impulses to the brain by cranial The functions of the nervous system are: • To receive stimuli from the external and internal Its function is to process information from the sense organs and relay it to the cerebral cortex.Nerve cells may be described as receivers and transmitters of information that allow an organism to respond appropriately. In the human body, the nervous system (which consists of the central and peripheral nervous system) is said to contain about 1020 individual neurons. Each of the neurons is...

In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.We have five sense organs in our body, and as the name suggests they help us to sense our surroundings and then our brain respond to them. 1. EYES : Provide us the ability to see. 2. NOSE : Help us to smell different fragrances.The nervous systems of molluscs correlate with lifestyle. Clams and chitons have little or no cephalization and simple sense organs. Sensory neurons transmit information from sensors that detect external stimuli (light, heat, touch) and internal conditions (blood pressure, muscle tension).They always carry information toward the central nervous system. Efferent (motor) neurons — unipolar cells that conduct signals away from the An insect's internal organs are largely innervated by a stomodaeal (or stomatogastric) nervous system. A pair of frontal nerves arising near the base...

central nervous system. NS division that consists of the brain and spinal cord. thalamus. relays sensory information, acts as a telephone contains nerves that branch throughout the body outside the CNS. sensory neurons. cells that carry information from sense organs to the central nervous.The nervous system is a network of interconnecting structures composed of different types of nerve cells called Neurons and Glial cells. This process is known as synaptic transmission. Neurons are found throughout the nervous system and innervate every other organ system of the human body.Divisions of the Nervous System Nerve Tissue (1) (2) Neurons Neuroglia Neuroglia  Neuroglia cells do not There are several differences between axons and dendrites: Axons Take information away from  Formed out of 3 ganglia, innervates sense organs and muscles of the mouthparts, salivary...There is peripheral nervous system (PNS) are neurons located outside the brain and spinal cord and which is the central nervous system [CNS].Revise coordination and control - the nervous system for GCSE Biology, AQA. The coordination centre, such as the brain, spinal cord or pancreas, which receives and processes information from receptors around the Information from receptors passes along neurones, as electrical impulses to co-ordinators such as the Sense organs contain groups of receptors that respond to specific stimuli.
