Multiple choice zoology nervous system neural tissue structure of neuron nervous tissues

Which of the following belongs to the neural tissues?

  1. Granulosa cells

  2. Cardiac cells

  3. Epithelial cells

  4. Nerve cells
Reveal answer Fill a bubble to check yourself
D Correct answer
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

  1. Contains a single axon

  2. Is found only in CNS

  3. Carries only sensory information

  4. Is a cablelike bundle of parallel axons
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Collateral fibers are branches that emerge from the main axon along its length, allowing a single neuron to communicate with multiple target cells.

Multiple choice zoology nervous system neural tissue structure of neuron nervous tissues

Centrosomes are absent in ______________.

  1. Nerve cells

  2. Epithelial cells

  3. Germinal cells

  4. All the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mature nerve cells (neurons) are specialized cells that have lost the ability to divide, and they lack centrosomes, which are required for cell division.

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

  1. cartilage

  2. Blood

  3. Lung

  4. Cardiac muscle
Reveal answer Fill a bubble to check yourself
C Correct answer
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

Reveal answer Fill a bubble to check yourself
A Correct answer
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'.
