Muscular tissues (textus muscularis) name a tissue, various on a structure and a parentage, but similar on ability to the expressed reductions. They provide movings to organism space in whole, its parts and movement of organs in an organism (heart, tongue, an intestine, etc.).
Two principles are put in a basis of classification of muscular tissues - a morpho-functional and a histo-genetic. According to a morpho-a functional principle, depending on structure of organellas of reduction, muscular tissues section on two subgroups.
The first subgroup - transversely striated (striated) muscular tissues (textus muscularis striatus). In a cytoplasma of their elements myosine filaments are constantly polymerized, form with actinide threads constantly existing myofibrils. The last are organised in characteristic complexes - sarcomeres. In the next myofibrils structural sub units of sarcomeres are located at identical level and frame cross-section striation. Striated muscular tissues are reduced faster, than smooth.
The second subgroup - smooth (not striated) muscular tissues (textus muscularis nonstriatus). These tissues are characterized by that out of reduction myosine filaments are depolymerized. In the presence of ions of calcium they polymerise and enter interaction with actin filaments. Myofibrils formed thus have no cross-section striation: at special colourings they are presented (smooth) threads in regular intervals painted on all length.
According to a histo-a genetic principle depending on development sources (embryonal germs) muscular tissues are sectioned into 5 types: mesenchimes (from desmal a germ in structure mesenchimes), epidermal (from a dermal ectoderm and from a prechordal plate), neural (from a nervous tube), coelomic (from a myoepicardial plate of a visceral leaf of a somite) and somatic (myotomes).

What kind of tissue is the Mammary Glands?
Mammary gland consist of glandular tissue and fatty tissue in them. Mammary glands are characteristic of mammals.
An extracellular ground substance is characteristics of?
The extracellular matrix is a characteristic of connective tissue.
Which is NOT a characteristic of a plant's vascular tissue It transports water and food inside the plant or It supports the plant's stems and leaves or It exposes the plant's leaves to the sun or It t?
"it transports water and food inside the plant" is a characteristic as xylem transports water and the phloem transports food in the form of sucrose. "it support the plants stems and leaves" is a characteristic of vascular tissue because the arrangement of the xylem and phloem provide it with strength and therefore support. the last one is then the wrong characteristic.
IN which type of connective tissue are the fibers dissolved in a liquid matrix?
Connective tissues have an extracellular matrix that gives them their characteristic properties. Blood is a liquid connective tissue that has a fluid matrix.
Which characteristic of life would include the process of photosynthesis?
A. Using energy
What is the most distinguishable characteristic of muscle tissue?
The most distingquishing characteristic of muscle tissue is the ablility to transform chemical energy into mechanical energy.
What is the tissue of the gland?
Mammary gland consist of glandular tissue and fatty tissue in them. Mammary glands are characteristic of mammals.
What kind of tissue is the Mammary Glands?
Mammary gland consist of glandular tissue and fatty tissue in them. Mammary glands are characteristic of mammals.
Haversian canals are characteristic of which tissue?
Haversian system is part of compact bone, which itself is a connective tissue.
What are the tissue characteristic?
Group of similar cells that perform a specialized function.
Is large amount of extracellular matrix a characteristic of epithelial tissue?
yeah
What characteristic does not describe cardiac muscle tissue?
Cardiac muscle tissue is specifically muscle tissue of the heart. It is smooth just like skeletal muscle tissue but has special characteristics that help it to contract at fast, steady rates.
What is the name for a group of cells that has the same structural characteristic and performs the same fuctions?
This is the definition of a tissue.
An extracellular ground substance is characteristics of?
The extracellular matrix is a characteristic of connective tissue.
What are the characteristic of a seed?
Seed plants have roots, stems, leaves, has vascular tissue, and flowers that produce seeds.
What characteristics of normal lung tissue are missing from diseased tissue?
the two main characteristics of normal lung tissue that may be affected in diseased individuals are either Compliance or Elasticity. compliance is the characteristic of lung tissue that allows it to expand elasticity is the characteristic of lung tissue that allows it go back to its former shape and size. elasticity is usually affected in chronic obstructive conditions like emphysema compliance is usually affected in restrictive lung dysfunctions like pulmonary fibrosis.
Which is NOT a characteristic of a plant's vascular tissue It transports water and food inside the plant or It supports the plant's stems and leaves or It exposes the plant's leaves to the sun or It t?
