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 else can I help you with?
The cells that transmit nerve impluses in the nervous system are?
The cells that transmit nerve impulses in the nervous system are called neurons. Neurons are specialized cells that are capable of generating and conducting electrical signals throughout the body. They form the basic building blocks of the nervous system and are essential for communication between different parts of the body.
What name of legs nerve?
The nerve that supplies sensation and movement to the leg is called the sciatic nerve. It is the largest nerve in the body and branches into smaller nerves that innervate different parts of the leg.
A collection of nerve fibers through which impulses travel between the central nervous system and other parts of the body?
This is the definition of a nerve. Nerves are composed of bundles of nerve fibers that transmit electrical signals to and from the central nervous system to control movement, sensations, and other bodily functions.
Is the skin on the different parts of the body different numbers of nerve receptors?
Yes, the skin on different parts of the body has varying densities of nerve receptors. Areas with a higher concentration of nerve receptors, like the fingertips and lips, are more sensitive to touch, temperature, and pain. Other areas, such as the back, have fewer nerve receptors and are less sensitive.
What at is a nerve stimulus?
A nerve stimulus is a signal or impulse that is transmitted along a nerve fiber, triggering a response in the body. This stimulus can be initiated by various factors such as touch, temperature, or pressure, and is essential for the communication between different parts of the nervous system.
The cells that transmit nerve impluses in the nervous system are?
The cells that transmit nerve impulses in the nervous system are called neurons. Neurons are specialized cells that are capable of generating and conducting electrical signals throughout the body. They form the basic building blocks of the nervous system and are essential for communication between different parts of the body.
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 name of legs nerve?
The nerve that supplies sensation and movement to the leg is called the sciatic nerve. It is the largest nerve in the body and branches into smaller nerves that innervate different parts of the leg.
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 is the form of message carried by a nerve cell called?
The form of message carried by a nerve cell is called an action potential. An action potential is a brief electrical signal that travels along the nerve cell's axon, allowing for communication between different parts of the nervous system.
Where are nerve cells found?
Nerve cells, or neurons, are primarily found in the nervous system, which includes the brain, spinal cord, and peripheral nerves. They are responsible for transmitting signals throughout the body, facilitating communication between different parts of the nervous system and coordinating bodily functions. Neurons can also be found in ganglia, clusters of nerve cell bodies located outside the central nervous system.
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.
The branches out to form nerve fibers?
Nerve fibers form from the branching of nerve cells called neurons. These fibers transmit electrical impulses and allow communication between different parts of the nervous system. The intricate branching structure helps facilitate the rapid transmission of signals throughout the body.
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.
