nervous tissue is made up of two principal types of cells as neurons, and neuroglia. The nervous tissues work together and form the nervous system, which is essential for the functioning of the body.Complete answer:
|Points||Nervous tissue||Nervous system|
|Composition||Nervous tissue is made up of nerve cells called neurons.It also has neuroglia which supports and nourishes neurons.||The nervous system composed of neurons which work together in the body|
|Parts||Neurons have three parts though they are varying in appearance as a cell body, dendrite(s), and an axon||CNS includes the brain and spinal cord. Cranial and spinal nerves form the peripheral nervous system (PNS).|
|Types||Two types of cells present as neurons and neuroglia.Neurons are classified based on their function and shape. The neurons which take nerve impulses from the CNS to muscles or glands are called motor neurons. The neurons which take nerve impulses from sensory receptors to the CNS are called Sensory neurons.||There are two types of nervous systems: peripheral nervous system and Central Nervous system. |
|Function||They transmit nerve impulses||In the somatic system, nerves conduct impulses from sensory receptors located in the skin and internal organs to the CNS; nerves also conduct motor impulses from the CNS to the skeletal muscles.|
The Central Nervous system controls the endocrine system of the body. It detects the signals and communicates to CNS. It releases hormones, which act on the target gland for production of further hormones. This process is known as neuroendocrine system.Note:
Nervous tissues as neurons work together and communicate with CNS and PNS. Two types of cells present in nervous tissues as neurons and neuroglia.CNS includes brain and spinal cord. Cranial and spinal nerves form the peripheral nervous system.
