Answer 1

Answer:

Muscles..

Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion.

Types of Muscles..

In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart.

Properties of Muscles....

All muscle tissues have 4 characteristics in common:

excitability.

contractility.

extensibility - they can be stretched.

elasticity - they return to normal length after stretching.

$<marquee> properties of muscle are : -</marquee>$

They are primarily responsible for maintaining and changing posture.

• muscle maintain locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

[tex]{Type's of muscle}[/tex]

• Skeletal muscle or "voluntary muscle"

is anchored by tendons (or by aponeuroses at a few places) to bone and is used to effect skeletal movement such as locomotion and in maintaining posture.

• Smooth muscle or "involuntary muscle"

is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin (in which it controls erection of body hair).

• Cardiac muscle (myocardium),

is also an "involuntary muscle" but is more akin in structure to skeletal muscle, and is found only in the heart.

Internal structure of muscles are given in attachment ‼️
