What is the Acrosome? The acrosome is a specialized organelle found on sperm cells. It wraps around the head of the sperm and contains enzymes designed to help the sperm penetrate the egg by breaking down the proteins in the egg's cell wall.n a process known as the acrosome reaction, the sperm cell fuses with the egg, releases the enzymes, and enters the egg to complete fertilization. This structure is of particular interest to fertility specialists, as problems with the acrosome reaction can cause fertility issues.

Pingelap: Island of the Colorblind Congenital Achromatopsia is an extremely rare hereditary vision disorder that affects 1 person out of 33,000 in the United States . Congenital Achromatopsia is sometimes referred to as stationary cone dystrophy because it is not progressive nor does it lead to blindness . Coping with light sensitivity is the most significant problem faced by Achromats.

Acromegaly Definition and History Acromegaly is a hormonal disorder that results when a pituitary adenoma produces excess growth hormone (GH). It most commonly affects middle-aged adults and can result in serious illness and premature death. Overgrowth of bone and cartilage often leads to arthritis.

acrosome 1. acrosome-a process at the anterior end of a sperm cell that produces enzymes to facilitate penetration of the egg. sperm, sperm cell, spermatozoan, spermatozoon-the male reproductive cell; the male gamete; a sperm is mostly a nucleus surrounded by little other cellular material.crosome. n. 1. (Physiology) a cap-like structure on the tip of a spermatozoon that releases enzymes on encountering the ovum allowing fusion with the ovum in the sexual reproductive process; this part of the process is known as the acrosome reaction. [C19: from acro- + -some³].

4.4 The sperm cells meet the oocyte - the acrosome reaction The penetration of the pellucid zone. The enzymes that are released in the immediate vicinity of the pellucid zone by the acrosome reaction dissolve it locally and thus create a way through it for the sperm cells. A number of enzymes that have been released are involved.

Polysome A polyribosome (or polysome) is a complex of an mRNA molecule and two or more ribosomes that act to form polypeptide chains during active translation. Originally coined ergosomes in 1963, they were further characterized by Jonathan Warner, Paul Knopf, and Alex Rich.

Antikythera mechanism Front panel of a 2007 reproduction. The Antikythera mechanism is an mechanical calculator. It is also described as the first mechanical computer. It was discovered in 1901 in a shipwreck off the coast of Antikythera, Greece. A number of gears worked together, much like they do in a mechanical clock.

Acrosome In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.n Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).

Original articleOs acromiale, a cause of shoulder pain, not to be overlooked Os acromiale is a failure of fusion of the acromial process. It is usually asymptomatic and discovered by chance. When it is painful a differential diagnosis must be made in relation to the subacromial impingement syndrome. Unstable os acromiale is the cause of atypical scapulalgias.

autosome any chromosome that is not a sex chromosome and that appears as a homologous pair in a somatic cell. Humans have 22 pairs of autosomes, which transmit all genetic traits and conditions other than those that are sex-linked. Also called euchromosome [yoo′krōməsōm] . Compare sex chromosome. autosomal, adj. A non-sex (non-X, non-Y) chromosome which in normal humans is one of 22 pairs of chromosomes.

What is proteomics? Proteomics is the large-scale study of proteomes. A proteome is a set of proteins produced in an organism, system, or biological context. We may refer to, for instance, the proteome of a species (for example, Homo sapiens) or an organ (for example, the liver). The proteome is not constant; it differs from cell to cell and changes over time.
