(a) simplereflex
(b) conditionalreflex
(c) neurotransmitter function
(d) autonomic nerve conditions
Show Answer & Explanation

Answer: (a) simplereflex

Explanation:
1. The leg movement of a frog with a crushed brain is a simple reflex, because the reflex arc passes through the spinal cord only.
2. It does not need the brain.

Teacher's Note:
1. Conditioned reflexes need the brain.

(b) vagus nerve
(c) trigeminal nerve
(d) olfactory nerve
Show Answer & Explanation

Answer: (c) trigeminal nerve

Explanation:
1. The fifth cranial nerve is the trigeminal nerve, with ophthalmic, maxillary and mandibular branches.
2. Optic is the second, vagus the tenth and olfactory the first.

(d) on the yellow spot
Show Answer & Explanation

Answer: (c) in front of the retina

Explanation:
1. A person who needs concave lenses has myopia.
2. The image of a distant object falls in front of the retina.

Teacher's Note:
1. The concave lens diverges rays so that they focus on the retina.

Question 9: Unidirectional transmission of a nerve impulse through nerve fibre is due to the fact that
(a) nerve fibre is insulated by a medullary sheath.
(b) sodium pump starts operating only at the cyton andthencontinuesintothe nervefibre.
(c) neurotransmitters are released bydendrites and not by axon endings.
(d) neurotransmitters are released bythe axon endings and not by dendrites.
Show Answer & Explanation

Answer: (d) neurotransmitters are released bythe axon endings and not by dendrites.

Explanation:
1. A nerve impulse travels in one direction through the nerve fibre because neurotransmitters are released only from axon endings and receptors are on the next dendrite.
2. So the synapse allows only one-way transmission.

Teacher's Note:
1. Medullary sheath only speeds conduction.

Question 10: A person, who shows unpredictable moods, outbursts of emotion, quarrelsome behaviour and conflicts with others, is suffering from

Question 12: Hearing impairment affects which part of brain?
(a) Frontal lobe
(b) Parietal lobe
(c) Temporal lobe
(d) Cerebellum
Show Answer & Explanation

Answer: (c) Temporal lobe

Explanation:
1. The temporal lobe of the cerebrum contains the auditory area, so hearing impairment is linked to it.
2. The frontal lobe controls speech and thought, the parietal lobe sensation and the cerebellum balance.

Teacher's Note:
1. Learn the lobes with their functions.
