A dendritic cell is a specialized

A. Mature adipose cells are highly mitotic:Mature adipocytes do not actively divide. Instead, new adipocytes are formed from precursor cells, and mature ones primarily increase in size rather than number.

B. Its primary function is to store triglycerides:Adipose tissue serves mainly as an energy reservoir by storing triglycerides. It also provides insulation, cushioning, and contributes to endocrine functions by releasing hormones like leptin.

C. Most of the cell volume is occupied by the nucleus:In adipocytes, the nucleus is pushed to the periphery of the cell by a large lipid droplet. The majority of the cell volume is taken up by stored fat, not the nucleus.

D. It is composed mostly of extracellular matrix:Unlike connective tissues such as bone or cartilage, adipose tissue has relatively little extracellular matrix. The tissue is mainly composed of densely packed fat cells.

A. squamous epithelial cell:Squamous epithelial cells form flat layers of tissue that provide a protective barrier. They are not involved in antigen presentation or immune surveillance like dendritic cells.

B. muscle cell:Muscle cells are specialized for contraction and movement. They do not participate in immune responses or capture antigens, so they are not related to dendritic cell function.

C. melanocyte:Melanocytes produce melanin to protect the skin from UV damage. While both are found in the epidermis, dendritic cells function in immune defense rather than pigmentation.

D. nerve cell:Nerve cells transmit electrical signals to communicate sensory or motor information. They do not process antigens or trigger immune responses, unlike dendritic cells.

E. macrophage:Dendritic cells are specialized antigen-presenting cells closely related to macrophages. They capture, process, and present antigens to T cells, initiating adaptive immune responses in the skin and other tissues.
