Answer:

Thick diameter, Myelinated

Explanation:

A alpha neurons conduct action potentials faster because of their large axon diameter and myelin.

  • The large diameter is less resistant to the flow of ions and allows for faster conductivity.
  • The myelin sheath is a layer of fat acting as to insulate the axon which helps increase signal conductance.

Answer: thick diameter, myelinated are needed for faster signal propagations.

Explanation:

These are the largest neuron in the spinal cord.  Based on structure their axons  are large , myelinated( surrounded with deposits of myelin sheath)and multipolar(many dendrites) .

These structures are  related to their functions, thus the big size is related to large diameter of the axon, while the multipolarity for integration of information from multiple neurons  need myelinated  axons for fast sultatory conduction during   receptions of  sensory inputs

Their major function is innervation of muscles fibre that are concerned with muscle contraction, where they form motor unit thus  reasons for above characteristics.

Therefore  Myelinated to allow fast salutatory conduction velocity  of  range of  80-120 m/s for action potential

and

large diameter of 13-20 micro meter which offers little resistance to flow of action potential are the correct answers

Sonja [21]

The question is correct but the option is incorrect. The correct option is as follows:

a) Expedited Review b) Not Human Subjects c) Convened Review d) Exempt Review e) Full board review.

Answer:

Full board review.

Explanation:

IRB ( Institutional Review Board) is mainly responsible for the protection and maintains the ethics that are involved in the research related to humans and other animals.

The full board review requires  more time that n the other type of review. This review is mainly done in the cases where the participants can get misleading information. This review includes the research that are based on to involve the judgement and involves less risk. The information given in the question explain the full board type review.

Thus, the correct answer is full board review.
