ANATOMY

Detailed explanation-1: -Stratum corneum (outermost layer) Stratum granulosum. Stratum spinosum. Stratum basale (innermost layer) Thus, a needle would pierce the forearm’s epidermal layers in the order: firstly, corneum, followed by granulosum, spinosum, and finally reaching the basale. Hence, this is the correct option.

Detailed explanation-2: -Answer and Explanation: A needle that pierces the epidermal layer of the forearm would pierce the following epidermal layers in order, C. Corneum, granulosum, spinosum, basale. The stratum corneum is the outermost layer of dead skin cells and option B is the only answer choice that begins with the stratum corneum.

Detailed explanation-3: -The dermis contains two layers (papillary, and the deeper layer, the reticular dermis). Beneath the dermis is the subcutaneous tissue (s.c.), composed of fatty tissue and nerves. The subcutaneous tissue is the threshold in which traditional needles pass through therefore creating pain.

Detailed explanation-4: -The correct answer is D). The layers of the skin from deep to superficial are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.

Detailed explanation-5: -stratum basale. stratum spinosum. stratum granulosum. stratum lucidum. stratum corneum.
