Apraxia involves an inability to undertake learned and purposeful activities such as dressing, cooking etc., and means that sufferers must rely increasingly on caregivers to help with these activities. Limb apraxia is a common symptom of left hemisphere damage and consists of a deficit in performing gestures to verbal command or imitation. One form of rehabilitation training for limb apraxia is:

Correct Answer: A

Rationale: Gestural training is a rehabilitation technique used to improve limb apraxia, a condition characterized by difficulty in performing purposeful movements. This training involves teaching individuals to recognize and execute appropriate gestures and postures, enhancing their ability to perform daily activities. By focusing on the coordination of movements and the context in which they are used, gestural training helps individuals regain functional independence and reduce reliance on caregivers.

Correct Answer: D

Rationale: Acetylcholinesterase is an enzyme that breaks down the neurotransmitter acetylcholine in the synaptic cleft. This breakdown is essential for terminating the signal and preventing continuous stimulation of the postsynaptic neuron. Acetylcholinesterase ensures that acetylcholine's effects are short-lived and precisely regulated, allowing for controlled neural communication. Dysfunction of this enzyme can lead to neurological disorders.

Correct Answer: A

Rationale: The brain and spinal cord are the primary organs of the central nervous system (CNS). The CNS is responsible for processing and integrating information received from the peripheral nervous system (PNS). The autonomic nervous system (ANS) is a division of the PNS, and cerebrospinal fluid (CSF) is a protective fluid surrounding the CNS. Therefore, CNS is the correct answer as it directly refers to the brain and spinal cord.
