Oocyte An oocyte (UK /ˈoʊəsʌɪt/, US /ˈoʊ.oʊ.saɪt/), oöcyte, ovocyte, or rarely ocyte, is a female gametocyte or germ cell involved in reproduction. In other words, it is an immature ovum, or egg cell. An oocyte is produced in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia. During oogenesis, the oogonia become primary oocytes.

Oocyte An oocyte is produced in the ovary during female gametogenesis. The female germ cells produce a primordial germ cell (PGC), which then undergoes mitosis, forming oogonia.During oogenesis, the oogonia become primary oocytes.uring the primary oocyte stage of oogenesis, the nucleus is called a germinal vesicle. The only normal human type of secondary oocyte has the 23rd (sex) chromosome as 23,X (female-determining), whereas sperm can have 23,X (female-determining) or 23,Y (male-determining).

lymphocyte lymphocyte(s) (lim´fōsīt), n a form of white blood cell originating in lymphoid tissues; possesses a single spherical nucleus and a nongranular cytoplasm. It constitutes 25% of the white blood cells. Some, along with plasma cells and histiocytes, are found in clinically normal gingivae.

Definitions &Translations Oogenesis, ovogenesis, or oögenesis /ˌoʊ.əˈdʒɛnᵻsɪs/ is the creation of an ovum (egg cell). It is the female form of gametogenesis; the male equivalent is spermatogenesis. It involves the development of the various stages of the immature ovum. 1 Oogenesis in mammals.

Myocyte A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue.Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.ardiomyocytes are the muscle fibres that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the peristalsis contractions in the oesophagus and stomach.

ovum The term ovum is usually restricted to the single female sex cell, but the term egg, in its common use to indicate a bird's egg, refers to a more complex structure, only part of which is produced in the ovary of the bird.The ovum of such an egg is a cell swollen with yolk material. gamete, ovum or sperm, contains half the number of chromosomes found in the body cells of the parent, i.e., the gamete is haploid.

Oogenesis - Anatomy & Physiology Oogenesis is the process of producing the female gametes, the Ovum, from the primordial germ cells. The majority of the steps in oogenesis, up to the point of producing primary oocytes, occur pre-natally. Therefore, females are born with all of the Primary Oocytes that they will ever have as primary oocytes do not divide further.

Ovulation Developing egg cells inside the ovaries are called oocytes, and they are held in follicles, which are fluid-filled sacs, within the wall of the ovary. Each follicle will have only one oocyte, and only some of these will develop into eggs.

- The Beginning of Life. An oocyte is the very beginning of human life – in the simplest of terms, it is an immature egg cell. Throughout the process of ovulation, this immature egg cell eventually matures and becomes an ovum, or egg. For human females, ovulation occurs mid-way through their monthly cycle, which is typically around 28 days.

Egg cell In animals, egg cells are also known as ova (singular ovum, from the Latin word ovum meaning egg or egg cell).The term ovule is used for the young ovum of an animal.he ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 0.12 mm in diameter.

The ovaries are two small organs, about the size of your thumb, that are located in the female pelvis. They are attached to the uterus, one on each side, near the opening of the fallopian tube. The ovaries contain the female gamete cell, called the oocyte. In non medical terms, the oocyte is called the âeggâ. The eggs are stored within follicles in the ovary. Within a woman's lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process. The large majority, however, will not reach full maturity. Most will die off in a process called atresia. Thus, only about 300-500 of these eggs will mature over a women's life span. The maturation of eggs typically takes about 14 days and can be divided into 2 distinct periods. During the initial period, many eggs, as many as 1000, begin to develop and mature. The second phase of development requires gonadal hormone stimulation to stimulate further development.

Osteocyte Osteocyte. An osteocyte, a star-shaped cell, is the most abundant cell found in compact bone. Cells contain a nucleus and a thin ring of cytoplasm. When osteoblasts become trapped in the matrix they secrete, they become osteocytes. Osteocytes are networked to each other via long... a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they secreted. Cytoplasmic processes of the osteocyte extend away from the cell...

- At birth, oogonia are no longer present. Each primary oocyte is surrounded by a single layer of squamous epithelial cells called follicular cells. The primary oocyte together with its follicular cells is called a primordial follicle. There are about two million primordial follicles with their primary oocytes in the ovaries at birth suspended in the first division of meiosis.
