What is the structure and function of monocytes?

Monocytes are a type of white blood cell. Like other white blood cells, monocytes are important in the immune system’s ability to destroy invaders, but also in facilitating healing and repair. Monocytes are formed in the bone marrow and are released into peripheral blood, where they circulate for several days.

Do monocytes have a round nucleus?

Monocytes can have a variety of nuclear shapes. Their nucleus can be round, clover-shaped, or lacy; it can resemble a lymphocyte’s small, round or slightly indented nucleus, or a granulocyte’s segmented nuclear appearance.

What best describes the nucleus of monocytes?

Which of the following best describes the nucleus of a monocyte? The correct answer choice is large and indented, with fine, “raked” chromatin (B).

What is the structure of monocytes?

Structure of Monocytes Monocytes are the largest cells in the peripheral blood, with the diameter ranging between 14-20 µm in diameter. The morphological features of the cells include an irregular cell shape, an oval or kidney-shaped nucleus, cytoplasmic vesicles, and a high nucleus to cytoplasm ratio (3:1).

What do monocytes look like?

Monocytes have abundant blue-gray cytoplasm containing many fine lilac granules. These give the cytoplasm a “ground glass” appearance. However, these granules may be difficult to see if the blood film is poorly stained. Frequently, cytoplasmic vacuoles are present.

What is the shape of monocyte nucleus?

Monocytes have a bilobed nucleus (Fig. 1c), which frequently presents in tissue sections and blood smears as a U- or kidney-shaped nucleus. The lobed structure arises in promonocytes, where an initial spherical nucleus acquires an indentation that develops into the separation of the lobes (Fawcett 1970).

What is S shaped cell?

Basophils have S-shaped nucleus. Basophils is also one of the types of white blood cells.
