When considering an RBC histogram, what can cause an elevation in the left side of the curve?
stepladder [879]

Answer:

Low mean corpuscular value can shift the curve to the left side.

Explanation:

RBC histogram may be defined as the process of plotting the number of blood cells on Y- axis and their relative size on X- axis. Modern automated haematology is used for the construction of RBC histogram.

The cell population of RBCs is similar in size but not equal to the size of RBC the curve can shift to either direction. The low MCV (mean corpuscular value) value can shift the the curve to the left side while considering an RBC histogram.

Describe the main structural features of the epidermis and explain the functional significance of each.
Valentin [98]

The main structure of epidermis is composed of 4 layers or strata. From bottom to top, these are:

  1. stratum basale attached to the basement membrane.
  2. two intermediate layers (stratum spinosum and stratum granulosum), and
  3. at the top is stratum corneum.
  4. There is also a 'thick skin' or the fifth stratum present at the feet and palm, known as stratum lucidum. It is present between the stratum corneum and the stratum granulosum.

Stratum basale is the deepest layer attached to the basement. Stratum spinosum makes the skin strong and flexible. Stratum granulosum prevents water loss from the body.  Stratum corneum acts as  a protective barrier on the outermost side of the skin. Stratum lucidum is made up of dead cells present only in thick skin.
