Different types of tissues can be found in different organs. There may be various sub-tissues within each of the primary tissues.

Cardiac muscle tissue, or myocardium, is a specialized type of muscle tissue that forms the heart. This muscle tissue, which contracts and releases involuntarily, is responsible for keeping the heart pumping blood around the body. The human body contains three different kinds of muscle tissue: skeletal, smooth, and cardiac. Only cardiac muscle tissue, comprising cells called myocytes, is present in the heart. In this article, we discuss the structure and function of cardiac muscle tissue.

Tissue (biology)

Bone tissue is continuously remodeled through the concerted actions of bone cells, which include bone resorption by osteoclasts and bone formation by osteoblasts, whereas osteocytes act as mechanosensors and orchestrators of the bone remodeling process. This process is under the control of local e. An imbalance between bone resorption and formation can result in bone diseases including osteoporosis. Recently, it has been recognized that, during bone remodeling, there are an intricate communication among bone cells. For instance, the coupling from bone resorption to bone formation is achieved by interaction between osteoclasts and osteoblasts. Moreover, osteocytes produce factors that influence osteoblast and osteoclast activities, whereas osteocyte apoptosis is followed by osteoclastic bone resorption. The increasing knowledge about the structure and functions of bone cells contributed to a better understanding of bone biology.

The structure of each tissue of the body is organised to carry out its own specific functions, and this is reflected in the arrangement of the cells and its histological appearance. As you should already be aware, different tissues are capable of different functions. However, these functions may be interrelated.

The term tissue is used to describe a group of cells that are similar in structure and perform a specific function. Histology is the the field of study that involves the microscopic examination of tissue appearance, organization, and function. Tissues are organized into four broad categories based on structural and functional similarities. The primary tissue types work together to contribute to the overall health and maintenance of the human body. Thus, any disruption in the structure of a tissue can lead to injury or disease. Epithelial tissue refers to groups of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands.

Tissue types

In biology , tissue is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues. The English word "tissue" derives from the French word "tissue", meaning that something that is "woven", from the verb tisse, "to weave". The study of human and animal tissues is known as histology or, in connection with disease, as histopathology.

Despite its complexity, the organs of the human body are composed of only four basic tissue types: epithelial, connective, muscular, and nervous tissues. Each tissue is an assemblage of similarly specialized cells united in performing a specific function.

The cells within a tissue share a common embryonic origin. From the evolutionary perspective, tissues appear in more complex organisms. For example, multicellular protists, ancient eukaryotes, do not have cells organized into tissues. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is characterized by specific functions that contribute to the overall health and maintenance of the body.

Он смотрел на нее с нескрываемым любопытством.  - Что ты сказала. Чем ты занята. - Я ничего не говорила, - ответила Сьюзан. Хейл удивленно поднял брови. - Ах какие мы скрытные.

Она улыбнулась и поудобнее устроилась в постели. - Ты мне только что приснился. Приходи поиграть. - На улице еще темно, - засмеялся. - А-ах, - сладко потянулась.  - Тем более приходи.

 - Какого черта вы не позвонили Стратмору. - Мы позвонили! - не сдавалась Мидж.  - Он сказал, что у них все в порядке. Фонтейн стоял, тяжело дыша. - У нас нет причин ему не верить.

 Чего вы от меня хотите. Беккер задумался: Я бы хотел, чтобы ты как следует вымыл голову, научился говорить по-человечески и нашел себе работу. Но решил, что хочет от этого парня слишком многого.

Оставался только один выход, одно решение. Он бросил взгляд на клавиатуру и начал печатать, даже не повернув к себе монитор. Его пальцы набирали слова медленно, но решительно.

ГЛАВА 33 Токуген Нуматака смотрел в окно и ходил по кабинету взад-вперед как зверь в клетке. Человек, с которым он вступил в контакт, Северная Дакота, не звонил. Проклятые американцы. Никакого представления о пунктуальности.

4.1 Types of Tissues

Вдалеке, метрах в пятистах, на фоне ночного неба возникли силуэты самолетных ангаров.

 Это был девиз туристского бюро Севильи. - Она назвала вам свое имя. - Нет.

 Это может быть не вашим делом! - раздался зычный голос у них за спиной. Мидж от неожиданности стукнулась головой о стекло. Бринкерхофф опрокинул директорский стул и бросился к двери. Он сразу же узнал этот голос. - Директор! - воскликнул он и, подойдя к Фонтейну, протянул руку.

А когда пыль осела, тело Танкадо попало в руки местной полиции. Стратмор был взбешен. Халохот впервые сорвал задание, выбрав неблагоприятные время и место. Получить ключ было необходимо, но Стратмор отлично понимал, что посылать глухого киллера в севильский морг было бы настоящим самоубийством.

Мысли ее вернулись к Дэвиду.

 - Думаю, коммандер мне его откроет. Разве не так, коммандер. - Ни в коем случае! - отрезал Стратмор. Хейл вскипел: - Послушайте меня, старина. Вы отпускаете меня и Сьюзан на вашем лифте, мы уезжаем, и через несколько часов я ее отпускаю.

 Восемь рядов по восемь! - возбужденно воскликнула Сьюзан. Соши быстро печатала. Фонтейн наблюдал молча.

Причастие. Он застонал. Проклятые испанцы начинают службу с причастия.

Обхватил ее своими ручищами. Да еще хвастался, что снял ее на весь уик-энд за три сотни долларов.

Note that each organ is made of multiple tissues and that their are variations on how the tissues are designed.

There are four types of tissues found in animals: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. In this lab you will learn the major.
