Understanding the Muscular System: Structure, Function, and Types

1. What are the types of muscle tissue?

Skeletal muscle, Cardiac muscle and Smooth muscle

Adipose tissue, Ligament tissue, Bone tissue

Muscle tissue is classified into three main types: Skeletal muscle, Cardiac muscle, and Smooth muscle. Adipose tissue, Ligament tissue, and Bone tissue are not types of muscle tissue.

Explanation

Muscle tissue is classified into three main types: Skeletal muscle, Cardiac muscle, and Smooth muscle. Adipose tissue, Ligament tissue, and Bone tissue are not types of muscle tissue.

2. What is the function of the muscular system?

Stores excess nutrients and releases them when needed.

Provides oxygen to the body and removes carbon dioxide.

Allows movememnt of the body and organs; helps circulate blood and move food through the digestive system

Aids in producing hormones and regulating body temperature.

The muscular system is responsible for movement and plays a crucial role in circulatory and digestive processes.

Explanation

The muscular system is responsible for movement and plays a crucial role in circulatory and digestive processes.

3. What are the characteristics of skeletal muscle?

Attached to the brain

Smooth muscle

Involuntary muscle

Skeletal muscles are not attached to the brain, they are connected to bones by tendons. They are also not smooth muscles, which are found in organs and blood vessels. Skeletal muscles are voluntary, different from involuntary muscles like the heart, and play a crucial role in movement and heat generation.

4. Draw a diagram of skeletal muscle showing the connective tissue.

List the types of muscle fibers found in smooth muscle.

Draw a diagram of cardiac muscle showing the connective tissue.

Describe the functions of skeletal muscle without including connective tissue.

5. What are the characteristics of smooth muscle?

No striations, involuntary (no consicious control)Found mainly in the walls of blood vessels and hollow organse.g. Stomach and Bladder

Has striations, voluntary (conscious control), found in skeletal muscles

No striations, voluntary (conscious control), found in the brain and spinal cord

Has striations, involuntary (no conscious control), found in cardiac muscle

Smooth muscle is characterized by its lack of striations, as compared to skeletal and cardiac muscles. It is also involuntary, meaning it is not under conscious control. Smooth muscle is primarily found in the walls of blood vessels and hollow organs like the stomach and bladder.

Smooth muscle is characterized by its lack of striations, as compared to skeletal and cardiac muscles. It is also involuntary, meaning it is not under conscious control. Smooth muscle is primarily found in the walls of blood vessels and hollow organs like the stomach and bladder.

6. Draw a smooth muscle cell in transverse cross section and frontal or sagittal plane.

Drawing a nerve cell

Drawing a cardiac muscle cell

Drawing a skeletal muscle cell

This question requires the ability to accurately depict the structure of a smooth muscle cell in specific cross sections and planes, which is necesssary for understanding anatomical features and functions.
