Question

структуры, образованныегладкой мышечной тканью и поперечнополосатой мышечной тканью

Answer 1

Гладкая мышечная ткань выстилает поверхности внутренних органов (например, мочевого пузыря), данная ткань сокращается медленно и плавно
 поперечнополосатой мышечной тканью образованы скелетные мышцы, входит в состав сердца
данная ткань сокращается быстро и интенсивнее

Answer 2

Поперечнополосатые мышечные тканиИмеется две основные разновидности поперечнополосатых (исчерченных) тканей — скелетная мышечная ткань и сердечная мышечная ткань.Гладкие (неисчерченные) мышечные ткани. Эти ткани характеризуются тем, что вне сокращения миозиновые филаменты деполимеризованы. В присутствии ионов кальция они полимеризуются и вступают во взаимодействие с филаментами актина. Образующиеся при этом миофибриллы не имеют поперечной исчерченности: при специальных окрасках они представлены равномерно окрашенными по всей длине нитями.В соответствии с гистогенетическим принципом в зависимости от источников развития (т.е. эмбриональных зачатков) мышечные ткани подразделяются на 5 типов:мезенхимные (из десмального зачатка в составе мезенхимы)эпидермальные (из кожной эктодермы и из прехордальной пластинки)нейральные (из нервной трубки)целомические (из миоэпикардиальной пластинки висцерального листка спланхнотома)соматические (миотомные)Первые три типа относятся к подгруппе гладких мышечных тканей, четвертый и пятый — к подгруппе поперечнополосатых.

Structures formed by smooth muscle tissue and striated muscle tissue

Smooth muscle tissue and striated muscle tissue are two types of muscle tissues found in the human body. They have different structures and functions. Let's explore each of them in detail:

Smooth Muscle Tissue: Smooth muscle tissue, also known as involuntary muscle tissue, is found in the walls of various organs and structures throughout the body. It is responsible for the involuntary movements of these organs. Here are some key points about smooth muscle tissue:

- Smooth muscle tissue is composed of elongated spindle-shaped cells. - The cells are uninucleated, meaning they have a single nucleus. - The cells lack striations or cross-bands, which gives them a smooth appearance under a microscope. - Smooth muscle tissue is found in the walls of organs such as the digestive tract, blood vessels, uterus, and respiratory airways. - It is responsible for various involuntary movements, such as peristalsis in the digestive system and constriction and dilation of blood vessels. - Smooth muscle tissue is controlled by the autonomic nervous system and hormones.

Striated Muscle Tissue: Striated muscle tissue, also known as voluntary muscle tissue, is responsible for voluntary movements of the body. It is found attached to the skeleton and is responsible for movements such as walking, running, and lifting. Here are some key points about striated muscle tissue:

- Striated muscle tissue is composed of long, cylindrical cells called muscle fibers. - The cells are multinucleated, meaning they have multiple nuclei. - The cells have a striped or striated appearance due to the arrangement of contractile proteins called actin and myosin. - Striated muscle tissue is attached to bones via tendons and is responsible for skeletal movements. - It is under voluntary control and is controlled by the somatic nervous system. - Striated muscle tissue can be further classified into two types: skeletal muscle and cardiac muscle.

Skeletal Muscle Tissue: Skeletal muscle tissue is the type of striated muscle tissue that is attached to the skeleton. It is responsible for voluntary movements and provides support and stability to the body. Here are some key points about skeletal muscle tissue:

- Skeletal muscle tissue is composed of long, cylindrical muscle fibers. - The fibers are multinucleated and have a striped appearance due to the arrangement of actin and myosin filaments. - Skeletal muscle tissue is attached to bones via tendons. - It is responsible for movements such as walking, running, jumping, and lifting. - Skeletal muscle tissue is under voluntary control and is controlled by the somatic nervous system.

Cardiac Muscle Tissue: Cardiac muscle tissue is another type of striated muscle tissue found in the heart. It is responsible for the involuntary contractions of the heart, which pump blood throughout the body. Here are some key points about cardiac muscle tissue:

- Cardiac muscle tissue is composed of branching, interconnected cells called cardiomyocytes. - The cells are uninucleated and have a striped appearance due to the arrangement of actin and myosin filaments. - Cardiac muscle tissue is found exclusively in the heart. - It is responsible for the rhythmic contractions of the heart, which pump blood. - Cardiac muscle tissue is under involuntary control and is regulated by the autonomic nervous system.

In summary, smooth muscle tissue and striated muscle tissue are two different types of muscle tissues with distinct structures and functions. Smooth muscle tissue is found in the walls of organs and is responsible for involuntary movements, while striated muscle tissue, including skeletal and cardiac muscle tissue, is responsible for voluntary and involuntary movements, respectively.
