  • Question 1
    1 / -0
    The cells which pass the instructions from brain to different parts of the body are called as
    Solution
    A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals. These signals between neurons occur via synapses, specialized connections with other cells. Neurons can connect to each other to form neural networks. Neurons are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS). 
    Therefore, the correct answer is option B.
  • Question 2
    1 / -0
    The sensitive membrane in our ears is called
    Solution
    • The eardrum is also called the tympanic membrane. 
    • It is present in the human ear. 
    • It receives sound vibrations from the outer air and transmits them to the auditory ossicles in the middle ear cavity. 
    • Hence its main function is to convert and amplify vibration in the air to vibration in the fluid. 
    Thus the correct answer is option C.

  • Question 3
    1 / -0
    Praveen is attempting the play cards (of different colours) sorting task. He starts off sorting the cards according to their colours, but when the experimenter changes the sorting criterion, Praveen starts sorting the cards instead according to the shapes on the cards. Praveen fails to detect this shift in strategy, so he continues to sort the cards by colour. Praveen has most likely suffered damage to which of the following region?
    Solution
    The frontal lobe is one of the most important parts of the brain. Injury to frontal lobe causes dementia and other severe diseases like Alzheimer's disease. It is important for frontal lobe to function properly for an individual to make good choices and recognize consequences.
    So, option B is the correct answer.
  • Question 4
    1 / -0
    The screen on which the images of the objects we see are formed is called as
    Solution
    Retina is a light-sensitive layer located at the back of the eye. It covers 65 percent of the interior surface of the eye. Rods and cones are the photosensitive cells in the retina that convert incident light into signals. These signals are carried to the brain by the optic nerve and the image is perceived.
    Thus the correct answer is option D.

  • Question 5
    1 / -0
    Nerve impulses are conducted towards the cell body by:
    Solution
    Dendrites are branched projections of the cell body. They receive information from other neurons via synapse and transmit it to the cell body.
    So, the correct answer is option C.
  • Question 6
    1 / -0
    Identify the labels of the diagram.

    Solution
    1 - Nucleus, 2 - Dendrite, 3 - Cell body, 4 - Axon, 5 - Nerve ending
    The nucleus is present in the main cell body. Dendrites are the projections of cell body that receive messages from other neurons and passes them to the cell body. Axon is the long extension of the nerve cell that transmits nerve impulses from the cell body to other neurons. At the end of the axon (nerve ending), the l impulse sets off the release of some chemicals. These chemicals cross the gap, or synapse, and start a similar electrical impulse in a dendrite of the next neuron.

  • Question 7
    1 / -0
    The spinal nerve pathway is a_______________-
    Solution
    • Each spinal nerve has motor and sensory nerve roots. They are like one-way streets.
    •  On a given neuron, the traffic can only travel in one direction to or from the CNS. 

    Therefore, the correct answer is option B.
  • Question 8
    1 / -0
    Sympathetic nerves in mammals arise from 
    Solution
    Sympathetic nerves in mammals arise from the thoracic lumbar region. It is represented by a chain of 21 sympathetic ganglia either side of spinal cord. It receives preganglionic sympathetic fibres from the spinal cord, which make these exit along with thoracic and lumbar region. It is a part of the nervous system that serves to accelerate the heart rate, constrict blood vessels and raise blood pressure. 
    Therefore, the correct answer is option D.
  • Question 9
    1 / -0
    The end of spinal cord resembles a____________________
    Solution
    • The spinal cord ends in a cascade of nerves resembling a horse"s tail, which is why this part is called the cauda equina. 

    Therefore, the correct answer is option A.
  • Question 10
    1 / -0
    A neuron transmits information through
    Solution
    Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain.
