Dehydration: Introduction, Classification and Causes

If a body loss an excessive amount of water than it requires for normal functioning, the condition is called dehydration. Minimum daily requirement of water is about one litre which may vary with the age and activity of the individual. The individual who remains active almost all the time require 2 to 3 litre of … Read more

Development of the Ear

There are three morphological divisions of the ear. They are: the external, middle and internal ear. These all divisions have a separate origin. Internal ear The formation of membranous labyrinth occurs from a specialized area of surface ectoderm overlying the developing hindbrain. At first, this area is apparent as a thickening called the otic placode. … Read more

Cell membrane: Structure and Functions

It is a protective outer covering sheath that envelopes the cell body. It is known by other name called plasma lemma and plasma membrane. It separates extracellular fluid (ECF) which is outside the cell and intracellular fluid that is inside the cell. It is a semi permeable membrane as it allows exchange of certain substances … Read more

Cytoskeleton and Its Components

The cellular organelle present throughout the cytoplasm is called cytoskeleton. The shape of the cell is determined by it and also gives support to the cell. It is of varying sizes and is a complex network of structures. It also helps in the cellular movements and also gives response to the cell to external stimuli. … Read more

Neuroglia: Introduction, Classification and Functions

The supporting cells of the nervous system that are non-excitable are called neuroglia or simply glia (glia=glue). They do not transmit nerve impulse (action potential) for which they are called non-neural cells or glial cells. They are about 10-15 times greater than the number of neurons. During infection, mostly they show or play an important … Read more

Platelets: Structure, Composition and Functions

Platelets also called thrombocytes are the formed elements of blood. They are small, non-nucleated colorless and moderately refractive bodies. They are considered to be the fragments of the cytoplasm being formed elements of blood. They are about 2.5µ (2 to 4µ) in diameter and 7.5 cu µ (7 to 8 cu µ) in volume. They … Read more

Erythrocyte Sedimentation Rate (ESR)

The rate at which the red blood cells or erythrocytes settle down is called ESR or erythrocyte sedimentation rate. In normal condition, red blood cells remain suspended uniformly in circulation which is called suspension stability of RBCs. Red blood cells settle down due to gravity with a supernatant layer of clear plasma when it is … Read more

Skin: Structure and functions

Skin is the largest of all the organ of our body that is not uniformly thick. It is thick at some places and at some places it is thin. In average, the thickness of the skin is about 1 to 2 mm. Generally, the skin is thick in the sole of the foot, palm of … Read more

Spermatozoon and Its Structure

A spermatozoon is a highly specialized, free swimming, actively motile cell which measures about 60 µm in length. The spermatozoon is made up of three parts. They are: a head, a neck and a tail or principal piece. Head is piriform in shape and measures 4 µm in length. It is derived from the nucleus, … Read more
