Questions Related to nervous tissues

Which of the following cells do not form layer and remain structurally separate?

  1. Epithelial cells

  2. Muscle cells

  3. Nerve cells

  4. Gland cells

Show answer
Correct Option: C
Explanation:
Nerve cells or neurons are the cells specialised to conduct an electrochemical current. Nerve tissue is made up of these cells. Only nerve cells do not form layers and remain structurally separate.
So the correct option is, 'Nerve cells'.

Neurilemma is outer covering of _______________.

  1. Blood capillaries

  2. Muscle fibre

  3. Intestine

  4. Nerve fibre

Show answer
Correct Option: D

Plasmalemma of axon is called ______________.

  1. Axolemma

  2. Neurilemma

  3. Sarcolemma

  4. None of these

Show answer
Correct Option: A

Neuro-fibrils are present in ___________.

  1. Cyton

  2. Muscles

  3. Bones

  4. Connective tissue

Correct Option: A

Function of nerves tissue is?

  1. Excitability

  2. Sensitivity

  3. Elasticity

  4. Contraction

Show answer
Correct Option: A
Explanation:

  • Nervous tissues are the class of specialized tissues majorly found in the central and peripheral nervous system. 
  • These tissues are made up of neurons and their supporting cells called neuroglia. 
  • These tissues are responsible for the control and coordination throughout the body. 
  • The nervous tissues or neurons are excitable cells that work on the basis of action potentials.

So, the correct answer is 'Excitability'.

Neural tissue is made up of

  1. Neutrons

  2. Electrons

  3. Neurons

  4. None of the above

Show answer
Correct Option: C
Explanation:

Neural tissue or nervous tissue is the main tissue component of the nervous system. It helps in the transmission of the nerve impulse from the sensory organs to the brain through the spinal cord and from the brain to the effector organ via the spinal cord.

So, the answer is 'Neurons'.

Cell bodies of neurons form

  1. Grey matter

  2. White matter

  3. Brain

  4. Spinal cord

Show answer
Correct Option: A
Explanation:

Grey matter refers to the non-myelinated neurons and other cells of the central nervous system (CNS). The grey matter is the main component of CNS, consisting of cell bodies, dendrites, glial cells, synapses and capillaries.

So, the answer is 'Grey matter'.

Which of the following conducts messages?

  1. Epithelial cells

  2. Cardiac cells

  3. Nerve cells

  4. Skeletal cells

Show answer
Correct Option: C
Explanation:
Human body contains millions of nerve cells that transmit such messages or impulses. Nerve cells are made up of dendrites, cell body and axon. The dendrites are branching fibres that receive the signals from the axon terminal of the other neuron and pass is to cell body. Cell body then pass the message further to axon.
So, the correct answer is 'Nerve cells'.

Which of the following is formed of neural tissue?

  1. Spinal cord and brain

  2. Kidneys

  3. Gall bladder and abdomen

  4. Esophagus and bronchi

Show answer
Correct Option: A
Explanation:

Neural tissue or nervous tissue consists of central nervous system and peripheral nervous system. The central nervous system is made up of the spinal cord and the brain. The peripheral nervous system consists of the nerves made up of nerve cells called neurons.

So, the correct answer is 'Spinal cord and brain'.

Which of the following horn has spinal cord tract?

zoology nervous system neural tissue structure of neuron nervous tissues

  1. Anterioar horn

  2. Posterior horn

  3. White matter

  4. Gray matter

Show answer
Correct Option: B
Explanation:
Posterior horn is a part of grey matter that has spinal cord tract. It receives the sensory information like touch and sensation via sensory neurons from different parts of the body.  It is also known as dorsal horn due to its presence in dorsal side of the body. 
So the correct answer is 'Posterior horn'.
