Executive functioning involves the integrated use of several cognitive processes by which people problem-solve, plan, initiate, organise and monitor goal-directed activities. Deficits in this collection of integrated skills involves which kind of training:

Correct Answer: A

Rationale: Goal Management Training (GMT) is a therapeutic approach designed to improve executive functioning by teaching individuals how to set, prioritize, and achieve goals. This training involves breaking down complex tasks into manageable steps, monitoring progress, and adjusting strategies as needed. GMT is particularly effective for individuals with neurological disorders or brain injuries that impair executive functions, helping them regain independence and improve daily functioning.

Correct Answer: B

Rationale: As potassium ions move out of the axon during repolarization, the oscilloscope records a return of the membrane potential to its negative resting state. This phase of the action potential is called repolarization and is essential for resetting the neuron so it can fire another action potential. Repolarization ensures that the neuron is ready to transmit subsequent nerve impulses.

Correct Answer: D

Rationale: The synapse is the tiny gap between neurons or between a neuron and its target cell, such as a muscle. It is the site where neurotransmitters are released to transmit signals from one cell to another. When an action potential reaches the axon terminal, neurotransmitters are released into the synapse and bind to receptors on the postsynaptic cell, triggering a response. The synapse is crucial for communication within the nervous system.

Correct Answer: D

Rationale: Schwann cells are responsible for forming the myelin sheath around axons in the peripheral nervous system (PNS). Dendrites, cell bodies, nuclei, and nodes of Ranvier are not directly myelinated by Schwann cells. Therefore, D is the correct answer.

Correct Answer: B

Rationale: The elevated ridges on the cerebral hemispheres are called gyri, and the shallow grooves are called sulci. Ganglia, tracts, receptors, and effectors are unrelated to these structures. Thus, B is the correct answer.
