What Contains many nuclei near the sacolemma? A. Skeletal muscle
B. Cardiac muscle
C. Smooth muscle

Answers

Answer:

Skeletal muscle contains many nuclei near the sarcolemma.

Explanation:

Skeletal muscles are voluntary muscles that are striated and multinucleated.  

These multiple nuclei are exclusively and uniformly distributed along the peripheral areas of the myofiber cell just near and underneath the sarcolemma, its plasma membrane.  

The positioning and movement of nuclei of a skeletal muscle during myogenesis is a unique process which takes place through five events – 1. centration, 2. alignment, 3. spreading, 4. peripheral movement, 5. anchoring.  

These nuclei facilitate skeletal muscles both functionally and structurally. They are multinucleated because of their sincitios nature arising from a fusion of numerous cells.  

Final answer:

Skeletal muscle cells contain many nuclei near the sarcolemma. The multiple nuclei result from the fusion of muscle progenitor cells during development. The nuclei help in regulating the metabolic needs of the muscle fiber.

Explanation:

The cell type that contains many nuclei near the sarcolemma is the skeletal muscle. Sacolemma is the name given to the cell membrane in a muscle cell. The presence of multiple nuclei in skeletal muscles arises from the way these muscles form. During development, myoblasts (muscle progenitor cells) fuse together to form long, multinucleated cells that become muscle fibers. Each nucleus regulates the metabolic requirements of the area of cytoplasm surrounding it, allowing the large skeletal muscle fibers to function effectively.

A phlebotomy technician should use a capillary collection instead of a venipuncture in which of the followingsituations?

Answers

The phlebotomy technician should use a capillary collection instead of venipuncture when the patient's veins are inaccessible, as shown in the first option.

Why can the patient's veins become inaccessible?

  • Due to the patient's excess fat.
  • Due to the low weight of the patient.
  • Due to dehydration.
  • Due to the inexperience of the medical team.

There are several situations in which the patient's veins are unavailable, but it is necessary for the medical team to have access to these veins to perform the necessary procedures for the patient's health.

When this happens, to optimize time and reduce interventions on the patient, the medical team can use phlebotomy, instead of venipuncture, to perform the procedure, performing a capillary collection.
