What level of the body are composed of tissue?
An organ is an anatomically distinct structure of the body composed of two or more tissue types. Each organ performs one or more specific physiological functions.
What two types of tissues compose most membranes?
There are two basic types of tissue membranes: connective tissue and epithelial membranes ([link]).
What is Class 9 muscle tissue?
Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Main function of muscular tissues is to provide movement to the body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement.
What is an example of muscle tissue?
1) smooth muscle. 3) Cardiac muscle. It can be found in the walls of the heart. Cardiac muscle tissues in heart contract to pump blood to all parts of the body.
How do you identify muscle tissue?
Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations.
What are the 4 types of muscle tissue?
Muscle is one of the four primary tissue types of the body, and the body contains three types of muscle tissue: skeletal muscle, cardiac muscle, and smooth muscle (Figure 7.2).
What are the 3 types of muscles tissue and examples?
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
What are 6 major types of muscles?

- Skeletal muscle.
- Smooth muscle.
- Cardiac muscle.
What do all muscle tissues have in common?
All muscle tissues have 4 characteristics in common: excitability. contractility. extensibility – they can be stretched.
What are the 4 functions of muscles?
The main functions of the muscular system are as follows:
- Mobility. The muscular system’s main function is to allow movement.
- Stability. Muscle tendons stretch over joints and contribute to joint stability.
- Posture.
- Circulation.
- Respiration.
- Digestion.
- Urination.
- Childbirth.
What is the main function of smooth muscle?
The primary function of smooth muscle is contraction. Smooth muscle consists of two types: single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can become stimulated in a synchronous pattern from only one synaptic input.
What connects bones and muscles together?
Tendons: Tendons connect muscles to bones. Made of fibrous tissue and collagen, tendons are tough but not very stretchy.
