Nervous System

Assertion: Corpus callosum is present in space between the dura mater and pia mater.
Reason: It serves to maintain the constant intracranial pressure.

Identify the correct functions of a nerve cell.

The neuromuscular junction is made up of the dendrite of a motor neuron and a muscle fibre.

Free nerve endings are most abundant in 

What is free nerve ending? What is its function in the skin?

In neurons, nucleus is located in the cell body.

Explain the function of nervous tissue.

Fill in the blank with the correct answer given in the bracket.

Nervous tissue sends the motor nerve impulses to _____ for action. (brain, spinal cord, muscles)

Nervous tissue cannot give a response.

Which of the following terms is/ are associated with the brain?

Dendrites receive information from other cells and transmit it to the cell body. Axons, on the other hand, conduct messages away from the cell body. The intercommunication junction between the axon terminal of one neuron and the dendrite of another neuron is called 'A'. The nerve impulse is transmitted across 'A' by a special chemical called 'B'.

What does 'B' stand for?

Dendrites receive information from other cells and transmit it to the cell body. Axons, on the other hand, conduct messages away from the cell body. The intercommunication junction between the axon terminal of one neuron and the dendrite of another neuron is called 'A'. The nerve impulse is transmitted across 'A' by a special chemical called 'B'.

What does 'A' stand for?

The number of receptors does not influence the efficiency of sense organs. 

The number of receptors in the sense organs is the same in different organisms. 

What are the main functions of the spinal cord?

Motor neurons conduct impulses from sensory organs to the brain and the spinal cord.

The motor nerves deliver the stimuli

Throwing ball and writing are involuntary actions.

The correct path of movement of nerve impulses in the following diagram is 

The cerebellum controls
