Nervous System Components Matching
This question requires matching components of the human nervous system with their respective functions.
Key Nervous System Divisions and Functions
- P. Sympathetic Nervous System: This system is primarily responsible for the body's response to stressful or emergency situations, commonly known as the 'fight-or-flight' response. This corresponds to function (iv).
- Q. Parasympathetic Nervous System: This system manages the body's 'rest-and-digest' functions, promoting calm and conserving energy under normal conditions. This corresponds to function (iii).
- R. Afferent Neurons: Also known as sensory neurons, these transmit sensory information from receptors towards the central nervous system (CNS). This corresponds to function (ii).
- S. Efferent Neurons: Also known as motor neurons, these carry signals from the central nervous system (CNS) out to effector organs like muscles and glands. This corresponds to function (i).
Matching Summary
Based on the definitions:
- P matches with (iv)
- Q matches with (iii)
- R matches with (ii)
- S matches with (i)
The correct combination is P-iv, Q-iii, R-ii, S-i.

S2: Patients with Wernicke's aphasia have trouble understanding what others say.- ________ in both lobes of the brain are responsible for coordination and interpretation of information as well as higher mental processing.
If Central Nervous System = Brain + Spinal Cord, then Peripheral Nervous System = ?
- Match the neurotransmitters with their functions
P. Acetylcholine (i) Movement and pleasure sensation Q. Dopamine (ii) Sleep, anxiety, and appetite R. Serotonin (iii) Attention and memory S. Norepinephrine (iv) Arousal and mood One, a sign language user with Broca's aphasia has difficulty producing signs. But the same signer has no difficulty in drawing pictures or picking up an object.
Two, a hearing person becomes paralysed in an accident and loses all motor ability, but is able to speak fluently.
What conclusions can we draw from these two cases about how language is represented in the brain?
