Fibres/Bodily Functions

Question 1

Explain how the muscular system helps to create movement

Answer 1

Skeletal muscles (voluntary muscles) work in pairs known as agonist and antagonist to help create movement in the human body

Question 2

Explain how the muscular system helps maintain posture

Answer 2

The muscular system helps to maintain posture by using muscle tone to keep an erect posture.

Question 3

Explain how the muscular system helps maintain bodily functions and body heat

Answer 3

Muscles maintain body heat by expelling heat such as when you shiver this is the muscles shaking trying to heat you up. The energy that muscles use to contract also help to create and maintain body heat.
The three types of muscles are involved with essential. bodily functions

Question 4

What are the three muscle types

Answer 4

Cardio, Smooth and skeletal muscle

Question 5

Skeletal Muscle

Answer 5

Voluntary muscle such as Bicep

Question 6

Cardiac Muscle

Answer 6

Only found in the heart, involuntary control

Question 7

Smooth Muscle

Answer 7

Found in the blood vessels and walls of the intestines, involuntary control

Question 8

The four tes of muscle fibre arrangements are

Answer 8

Multipennete, Bipennate, Unipennate, Fusiform

Question 9

Fusiform

Answer 9

Fusiform muscles run in the same direction as the tendon such as the Bicep bracchi. These types of muscles produce low force but can shorten over a large range

Question 10

Pennate

Answer 10

Pennate muscle fibres run at angles to the tendon and make up 75% of the skeletal muscles and produce great force.

Question 11

Four Functions of the Muscular System

Answer 11

Provide Movement
Maintain Posture
Retain Body Heat
Maintain Bodily Functions
