Questions Related to neural tissue

Which of the following belongs to the neural tissues?

zoology nervous system neural tissue structure of neuron nervous tissues

  1. Granulosa cells

  2. Cardiac cells

  3. Epithelial cells

  4. Nerve cells

Show answer
Correct Option: D
Explanation:
Nerve cells are also called neurons. They constitute the neural tissue. They are the largest cell in the human body. They are the structural and functional unit of the nervous system. 
So correct option is 'Nerve cells'.

A nerve

zoology nervous system neural tissue structure of neuron nervous tissues

  1. Contains a single axon

  2. Is found only in CNS

  3. Carries only sensory information

  4. Is a cablelike bundle of parallel axons

Show answer
Correct Option: A
Explanation:
Human brain consists of more than 100 billion nerve cells. These cells are further interlinked with each other and form complex nerve connections. A Nerve cell has many dendrites but has single axon through which electrical impulses are transmitted.
So the correct answer is 'Contains a single axon'.

Collateral fibres are given out along its way in ______________.

  1. Muscle fibre

  2. Axon

  3. Dendron

  4. Dendrites

Show answer
Correct Option: B

Centrosomes are absent in ______________.

  1. Nerve cells

  2. Epithelial cells

  3. Germinal cells

  4. All the above

Show answer
Correct Option: A

Which of the following is not considered to be a tissue?

zoology nervous system neural tissue structure of neuron nervous tissues

  1. cartilage

  2. Blood

  3. Lung

  4. Cardiac muscle

Show answer
Correct Option: C
Explanation:

Cartilage is supportive non-living soft connective tissue

Blood is fluid connective tissue
Cardiac muscle is a tissue made of cardiac cells
So, the correct option is 'Lung', which is an organ made of multiple tissue

The largest number of cell bodies of neurons in our body is found in:

  1. brain

  2. tongue

  3. kidneys

  4. stomach

Show answer
Correct Option: A
Explanation:

The largest number of cell bodies of neurons in our body is found in the brain, the human brain has approximately 86 billion neurons.

So, the correct option is 'brain'.
