Anatomical term - Flexion
Bend limb / joint
Anatomical term - Extension
Straighten Limb / Joint
Anatomical term - Abduction
Move away from mid line
Anatomical term - Adduction
Return to mid line
Anatomical term - Rotation
Turn in / out
Anatomical term - Supination
Rotate up / out
Anatomical term - Pronation
Rotate down / over
Anatomical term - Position
Location (of muscle)
Anatomical term - Action
What muscle does (movement)
Anatomical term - Origin
Fixed end of muscle
Anatomical term - insertion
Moving end of muscle
Anatomical term - Attachment
Point where muscle is attached to bone (by tendon / ligament)
Body System - Lymphatic
Lymph fluid / capillaries / vessels / nodes / ducts / lymphoid tissue
Drains excess fluid
Removes cellular waste
Produces antibodies
Transports fats
Body System Urinary
Kidneys / Ureters / Bladder / Urethra
Removes waste products from blood
Eliminates waste (via Urine)
Controls body fluid balance, salt content and acidity
Body System - Integumentary
Skin / Hair / Nails
Sensation / Heat regulation / Protection / Excretion / Secretion / Absorption / Vit D production
Body system - Digestive
Teeth / mouth, Epiglottis, Oesophagus, Stomach, Small intestine, Large Intestine, Rectum / Anus
Breaks down food
Absorbs nutrients from food
Eliminates waste (feaces)
Body System - Nervous
Central nervous system (brain, spinal cord)
Sensory neurones (sensation)
Motor neurones (movement)
Regulates & controls body functions - consciously and unconsciously (autonomic nervous system)
Maintains homeostasis (state of internal balance)
Body System - Muscular system
Muscles - skeletal / smooth / cardiac
Movement
Muscle tissue characteristics
Shorten / contract
Are elastic - can stretch & return to original state
Respond to nervous stimuli
Muscle tissue / smooth / voluntary
Controlled unconsciously & carries out functions not consciously controlled
Located in digestive system (stomach, oesophagus, intestines), blood vessels, bladder.
Works for long periods of time without tiring
Muscle Tissue - Voluntary / Skeletal
Consciously controlled - works with bones for movement
Can work very hard for short periods / tires easily
Muscle tissue - Cardiac
Found only in the heart
Contracts without nervous simulation
Works tirelessly throughout life
Trapezius
A large kite shaped
muscle that covers the
back and sides of the
neck, shoulders and
upper back
Elevates and depresses
the shoulders, also
draws the head
backwards
Rhomboids
In between the scapula
and thoracic vertebrae
Braces shoulder and
rotates scapula
Latissimus dorsi
Large muscle which
extends from the
thoracic and lumbar
vertebrae
Helps pull the body
upwards when climbing,
draws shoulders/arm
down and backwards
Errector Spinae
Runs down the length of
the vertebrae
Extends the spine and
holds the body upright
Pectorals
Cover the chest
Draws the arm and shoulder in towards the chest
Intercostals
In-between the ribs,
running obliquely
downwards
Muscle of respiration, used to increase the thoracic cavity when breathing normally
Rectus abdominis (6 pack)
Extends the whole
length of the front
of the abdomen & is
divided into 4 sections
Flexes the trunk forwards,
extends the spine and
maintains upright posture
