Question

What constitutes malpighian layer ?

• A. Corneum lucidum
• B. Corneum spinosum
• C. Spinosum and basale
• D. Basale granulosum

Answer 1

The Correct Option is C

The malpighian layer, also known as the stratum germinativum, is an essential component of the epidermis in skin anatomy. It consists of two specific layers:
1. Stratum Spinosum: This layer is located just above the stratum basale and is characterized by its spiny appearance due to the presence of intercellular bridges called desmosomes. These connections play a crucial role in providing structural support and facilitating communication between cells.
2. Stratum Basale: Also referred to as the basal layer, this is the deepest layer of the epidermis. It is composed of a single row of columnar or cuboidal cells that actively divide and produce new keratinocytes, which then move upward to form the upper layers of the epidermis.
The correct composition of the malpighian layer is thus "Spinosum and basale" as it involves both the stratum spinosum and the stratum basale, responsible for the regenerative and structural functions of the epidermis.
