The muscular system

Question 1

Basic function of muscle

Answer 1

Provides motor power for all movements and functions of the body parts.

Ability to contract actively to provide the force for movement and function
of the body.

They act both voluntary and involuntary

Acts as the framework for the entire body.

Question 2

3 different types of Muscle

Answer 2

Smooth muscle

Skeletal muscle

Cardiac muscle

Question 3

Function of smooth muscle

Answer 3

Form the soft body organs like stomach,
intestine – your digestive systems as well as blood vessels,
urinary and reproductive systems.

Is categorised as involuntary, part of the autonomic nervous
system.

They do not have any striation in contrast to the
other two types of muscles.

Question 4

Function of skeletal muscle

Answer 4

Creates movement in the body – this
movement is possible due to the skeletal muscle crossing over
joints and attaching to bones via tendons.

There are more than 600 skeletal muscles, making up 40 percent
of the body weight.

When the nervous system signals the muscle to contract, groups
of muscles work together to move the skeleton.

Skeletal muscle is categorised within the Somatic Nervous system, which means
through conscious or voluntary control can they be moved.

Question 5

Function of cardiac muscle

Answer 5

Categorised as involuntary muscle.

Found in the walls of the heart and creates
the steady, rhythmic pulsing that pumps blood and oxygen
through the body as well as creating electrical impulses that
produce the heart’s contractions.

This is controlled and functioned through the Sinoatrial Node (SAN) which is the
heart’s pacemaker.

The heart is set to contract 72 bpm through the activity of the
SAN and this rhythmic is called autorhythmic.
