Which of these processes does the muscular system not really help with
Heart beating
Circulation
Vision
Digestion
Cardiac Muscle is
(a)
Involuntary
No control over it
Intestines
Respiratory system
works automatically
Heart
Atrium and aorta
Voluntary
Muscles
Can control it
Match the following
Isometric Contraction
Force developed, no change in length
Agonist
Prime movers
Antagonist
relaxes
Synergist
assists the agonists
Stabiliser
Provides support in holding the body
Skeletal muscles are
attached to muscles via ligaments
Voluntary
Involuntary
attached to bones via tendons
Nervous Control is where
nerve stimuli control muscle action
can increase in size (growth) with an increase in activity muscle
muscles can return to their original size and shape once stretched
muscles can decrease in size (waste) as a result of injury, illness or lack of exercise.
In the "reciprocal inhibition" relationship the muscle causing the movement is known as (a)
Label the Muscular System

Label the point of origin and insertion for both the bicep and tricep
Bicep origin
Bicep insertion
Tricep Origin
Tricep Insertion
Explain the Henneman Principle with an example
Mark the correct position for the agonist and antagonist in elbow extension and elbow flexion
Match the following
Type 2A Fast twitch
both aerobic and anaerobic
Type 2B
Anaerobic and fast contraction
Type 1
High fat stores and contract slowly
Fusiform muscles are desgned for
strength and power
have three categories
come from the main tendon
mobility but produce low force
How many muscles are in the human body?
350
640
650
620
Involuntary means
We have control over it
Purposely do something of our own making
Happens by itself naturally
Happens by itself naturally
Smooth muscle is found in
Intenstines
Heart
Respiratory system
bones
Blood vessels are examples of what type of muscle
Smooth
Cardiac
Skeletal
Involuntary
Contractility is where
Muscles return to their original size
muscles can increase in size (growth) with an increase in activity.
nerve stimuli control muscle action.
muscles contract and become thicker
Extensibility
muscles can decrease in size (waste) as a result of injury, illness or lack of exercise.
muscles can increase in size (growth) with an increase in activity.
muscles have the capacity to stretch when a force is applied
nerve stimuli control muscle action.
During a bicep curl on the way up what is the bicep doing
Contracting concentrically
acting as the antagonist
Acting as the prime mover
Contracting eccentrically
During the upwards phase of the push up what role is the triceps playing
Agonist
Antagonist
contracting isotonically
Contracting isometrically
Fusiform muscles are
run opposite way to the tendon
Run opposite way to the ligament
short and thick
Long and thin
Pennate muscles
designed for strength and power
come from the main tendon
Mobility but low force
balance of strength, power and mobility
Endomysium are
bundle of muscle fibre that run length of the muscle
Connective tissure that surronds each fasiculi
connective tissue that surronds muscle fibre
connective tissue that covers entire muscle belly
Myofibrils are
muscle fibres that cover the cardiac muscle
muscle fibres that run along some of the muscle
smaller fibres that make up each of the muscle fibres
muscle fibres that relax the muscle
