Aging boom will affect the health care professional and healthcare in an uncertain way. This area is not a simplest one that a prediction can be made about future.
As we can see that chronic disease has become common among the old age peoples. More than half of the person above age 60 has one of the chronic diseases like hypertension diabetes, heart disease, etc.
There is a strong chance of many healthcare profession to be emerged in the future like health assistant, personal nurse, physician assistant, personal physical therapist, etc.

b-replacement with scar tissue rather than skin
c-excessive growth of replacement tissue
d-displacement of skin cells into other body tissues
Answer:D
Explanation: Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells
Excessive growth of replacement tissue could be expected from a skin injury if the tissue has lost the normal cell characteristic of contact inhibition. This could lead to the cells dividing and proliferating without acknowledging the usual cellular boundaries, possibly resulting in an overgrowth or benign tumor.
If a tissue loses the characteristic of contact inhibition, it would disobey the fundamental constraint that checks the cells from multiplying once they touch each other. This phenomenon significantly contributes to maintaining the integrity and organization of tissues and possesses great relevance to wound healing. Considering this, the expected response to a skin injury where the tissue lacks contact inhibition would be (c)-excessive growth of replacement tissue. The cells would continue to divide and proliferate disregarding the regular cellular boundaries, which can lead to an overgrowth, or in other terms, a benign tumor.

The correct answer is blood vessels which carry blood toward the heart.
B. Cardiac muscle
C. Smooth muscle
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.
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.
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.
