Reflex arcs in which the sensory stimulus and the motor response occur on the same side of the body are:
(a) Contralateral
(b) Paraesthetic
c) Ipsilateral
(d) Monosynaptic.

검증된 단계별 안내

Step 1: Understand the terminology related to reflex arcs. Reflex arcs are neural pathways that control reflex actions, involving a sensory input and a motor output.
Step 2: Define 'contralateral' reflex arcs: these involve the sensory stimulus and motor response occurring on opposite sides of the body.
Step 3: Define 'ipsilateral' reflex arcs: these involve the sensory stimulus and motor response occurring on the same side of the body.
Step 4: Recognize that 'paraesthetic' is not a term used to describe reflex arc laterality, and 'monosynaptic' refers to the number of synapses in the reflex arc, not the side of the body involved.
Step 5: Conclude that reflex arcs where the sensory stimulus and motor response occur on the same side of the body are called 'ipsilateral' reflex arcs.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Reflex Arc

A reflex arc is the neural pathway that controls a reflex action, involving a sensory receptor, sensory neuron, integration center, motor neuron, and effector. It enables rapid, automatic responses to stimuli without conscious brain involvement.

Ipsilateral Reflex

An ipsilateral reflex occurs when the sensory input and motor output happen on the same side of the body. This means the stimulus and response are localized to one side, such as the knee-jerk reflex.

Contralateral Reflex

A contralateral reflex involves a sensory stimulus on one side of the body and a motor response on the opposite side. This type of reflex helps coordinate actions between both sides, like the crossed extensor reflex.
