Question

Explain to your best understanding

a) Exocrine gland

b)Sensory Neuron

c)Motor Neuron

Answer 1

The detailed explanations for the following care given below:

a) Exocrine glands: are glands which secrete substance such as sweat,saliva,tears and release them into the epithelial surface with the help of a duct or an opening. They are the glands of external secretion. The Exocrine glands are of three types :

* Holocrine glands

* Merocrine or Eccrine glands

* Apocrine glands

The main function of Exocrine gland is to secrete enzymes, ions, water, mucins and other substances into digestive tract.

b) Sensory Neurons: are also known as afferent neurons. They are nerve cells within the nervous system which is located in the spinal ganglia. It helps to convert the external stimuli from the organisms environment into internal electrical impulses.

c)Motor neurons: are neuronal cells located inthe central nervous system. It can connect to muscles, glands and organs. These neurons transmit impulses from spinal cord to skeletal muscles.
