The Central Nervous System (CNS) comprises of 4 main parts; the forebrain, midbrain, hindbrain and spinal cord. All four parts and linked together and each tend to control specific parts of the vertebrate. In humans the forebrain is the most developed of the 'three brains' and allows us to hold a stronger understanding of our surrounded compared to that shown by other vertebrates.
There are two main categories of nerves which carry nerve impulses in and out of the CNS, spinal and cranial.
Cranial nerves are nerves which emerge from the brain stem (considered to be part of the midbrain), and are one of three types. Sensory, which carries nerve impulses into the CNS. Motor, which carries nerve impulses away from the CNS. And mixed, which carries nerve impulses both into and away from the CNS.
Spinal nerves are located in the vertebras of the spin and contain sensory neurons which are located in the dorsal roots, motor neurons which are located in the ventral roots and relay neurons which are located in the grey matter.

What parts of the central and peripheral nervous system have to be functioning for the senses of hearing and vision?
Trigeminal nerve
A collection of nerve fibers through which impulses travel between the central nervous system and other parts of the body?
nervous system
Is the skin on the different parts of the body different numbers of nerve receptors?
Yes, your lips actually have the greatest number of nerve (sensory) receptors followed by your hands. Conversely, areas such as your back are not nearly as sensitive to sensory stimulation.
Where do chemical messages originate from?
Chemical messages, also known as neurotransmitters, originate from the nerve cells in the brain or other parts of the nervous system. These chemical messengers are released at synapses, which are the junctions between nerve cells, to transmit signals from one nerve cell to another. Different neurotransmitters have specific functions and play a crucial role in regulating various physiological and cognitive processes in the body.
What is the different parts or organs involved in respiration system and their functions?
lungs
What parts that make up the nervous system?
nerve cells called neurons
What parts of the nervous system controls digestion?
The parasympathetic nervous system is responsible for digestion. The GI tract is innervated by the Gastric nerve, otherwise known as the Vagus nerve.
What are the parts f nerve system?
it is made up of the brain,the spinal cord, and the nerves
What are the cells that transmit nerve impulses between parts of the nervous system?
yes
What parts of the central and peripheral nervous system have to be functioning for the senses of hearing and vision?
Trigeminal nerve
What are some parts of the frog's nervous system?
Olfactory nerve, Optic nerve, Nasal sack, Trigeminal nerve, Gasserian ganglion, Facial nerve, Auditory nerve, Tympanic membrane, Glossopharyngeal nerve, pneumogastric nerve, First spinal nerve, Branchial enlargement, Branchial nerve, Third spinal nerve, fourth spinal nerve, fifth spinal nerve, sixth spinal nerve, seventh spinal nerve, eighth spinal nerve, ninth spinal nerve, tenth spinal nerve, Femoral nerve, Sciatic nerve, Sympathetic nerve trunk, Lumbar enlargement, Sympathetic ganglia, and Filum terminale.
A collection of nerve fibers through which impulses travel between the central nervous system and other parts of the body?
nervous system
Is a nerve a gamete?
No. A nerve is made up of neuron cells, and is part of the nervous system. A gemete is a different sort of cell, such as a sperm or egg, that is part of the reproductive system.
Can the nervous system repair its cables?
The nervous system is comprised of nerves called neurons, not 'cables'. Different nerve cells can reproduce to create newer nerve cells to replace damaged cells.
The sensory and motor nerve fibers that go from the brain and spinal cord to all parts of the body makeup which system?
Peripheral nervous system.
How many parts does your digestive system have?
The digestive system has several different parts. Some of the associated parts in the system are the mouth, esophagus, stomach and intestines.
Do Sensory nerve cells carry information from all sensory receptors to the immune system.?
Not all sensory receptors communicate with the immune system. Nerve cells carry information to various parts of the nervous system, eventually communicating with the brain or spinal cord.
