>Cardiac muscle is characterised by long, cylindrical, branched multinucleate muscle fibres with an indistinct sarcolemma Cardiac muscle is involuntary in nature. It never experiences fatigue Cardiac muscle occurs exclusively in the heart Connective tissue is the most abundant tissue in t..

> Striated muscle fibres have properties like excitability and contractibility. These are stimulated by a stimulus, which results in muscle contraction. Most accepted theory of muscle contraction is sliding filament theory . Many physical and biochemical changes occurs during muscle contr..

Areolar tissue is the most common and the most widely distributed type of connective tissue. It has a soft, homogeneous matrix in which both fibres and cells are embedded. The fibres in the matrix are of two types-white and yellow fibres...

It is also known as heart muscle. The cardiac muscle fibres do not form fasciles. They are arranged in the form of a network. The muscle fibres are elongated, cylindrical and branched. The branches become inter-connected with one another to form a network. The space between the ..

Flora refers to plant species and fauna refers to animal species. The term biota includes both plant as well as the domesticated and wild species of animals. Our country has a rich diversity of flora and fauna. There are over 45,000 plant species and 81,251 animal spec..

It is also called unstriped or nonstriated or involuntary or visceral muscle. The smooth muscle always occurs in the form of thin sheets. Each sheet has a large number of muscle fibres that are held together by a transparent connective tissue covering. The individual muscle fibres..

Fibrous tissue is a modification of the areolar tissue in which the matrix predominantly contains white fibres. Yellow fibres are reduced. Hence, the tissue becomes rigid and is known for its tensile strength. The fibrous tissue forms structures called tendons, which connect mu..

This requirement is the type of food required during the lactation period. Animal feeds have two main contents: Roughage This includes fibres like green fodder, silage, hay and leguminous plants like berseem, lucerne and cowpea. Concentrates This contains high content of pr..

. Each centriole is made up of nine microtubule triplets, which lie evenly spaced in a ring. There are no microtubules in the center (9+0 arrangement). Centrioles are involved in organizing the spindle fibres and astral rays during cell division in animal cells. They provide bas..
