1) Applied Anatomy & Physiology Flashcards
What are the 4 classifications of bone?
Long
Short
Flat
Irregular
What are long bones used for?
Movement, shape, blood cell production, mineral storage
What do tendons do?
Tendons attach muscle to bone
What do ligaments do?
Ligaments connect bone to bone
What bones are located in your leg?
Femur, fibula, tibia
What bones are located in your arm?
Humerus, ulna, radius
What is a joint?
A joint is where two or more bones meet
What are the 6 functions of the skeletal system?
Support Mineral Storage Blood Cell Production Movement Shape Protection
What is cartilage?
A protective layer that covers the end of each bone to stop them rubbing together
What is a joint capsule?
The joint capsule is tough, fibrous and surrounds the joint, it is lined with a synovial membrane
What do synovial membranes do?
Synovial membranes produce an oily substance called synovial fluid
What does synovial fluid do?
Synovial fluid keeps joints well lubricated to stop them wearing down and rubbing together
What do ligaments provide?
Ligaments provide strength and keep the bones in place (prevents dislocations)
What does bursae do?
Bursae are small bags of synovial fluid that reduce friction in a joint, they act like an airbag cushioning impacts
What are the features of a synovial joint?
Bursae
Joint Capusle
Ligament
Cartilage
What is the calf bone?
The calf bone is the fibula
What is the shin bone?
The shin bone is the tibia
What are the 6 ball and socket joint movements?
Flexion Extension Abduction Adduction Rotation Circumduction
What is rotation?
Rotation is the turning of a limb around its axis
What is adduction?
Adduction is the movement of a limb towards the midline of your body
What is abduction?
Abduction is the movement of a limb away from the midleine of your body
What is the plantar flexion agonist?
The plantar flexion agonist is the gastrocnemius
What is the knee extension agonist?
The knee extension agonist is the quadriceps
What is the elbow extension agonist?
The elbow extension agonist is the triceps
What is an isotonic eccentric contraction?
A isotonic eccentric contraction is when a muscle extends
What is an isotonic concentric contraction?
An isotonic concentric contraction is when a muscle shortens
What is an isometric contraction?
An isometric contraction is when a muscle stays the same length
What is the shoulder blade know as?
The scapula
Where are ball and socket joints located?
Hip
Shoulder
What bones make the hip joint?
Femur
Pelvis
What bones make the shoulder joint?
Scapula
Clavicle
Humerus
What is flexion at the hip?
Raising your knee out in front of you
What is flexion at the shoulder?
Raising your arm out in front of you
What is extension at the hip?
Pushing your heel back behind you
What is extension at the shoulder?
Pushing your arm back behind you
What is the prime mover for muscles?
Agonist
What muscles are used to move the elbow?

What muscles are used to move the hip?
Hip flexors
Gluteals
What muscles are used to move the shoulder?
Latissimus dorsi
Deltoid
What muscles are used to move the knee?
Hamstrings
Quadriceps
What muscles are used to move the ankle?
Gastrocnemius
Tibialis anteior
What contractions are we always stationary during?
Isometric contractions
What is the ordered pathway of air?
Mouth or nose Trachea Bronchi (2) Bronchioles Alveoli (150 million each)
What is the trachea lined with?
Cilia which catch dust particles
How are lungs adapted for gaseous exchange?
Contains millions of alveoli
Good blood supply
Large surface area
What causes the lungs to have a large surface area?
There are millions of tiny alveoli
Why is diffusion distance small in the lungs?
Capillaries are only 1 cell thick
What carries oxygen around the body?
Haemoglobin
What does oxygen bind to haemoglobin to create?
Oxyhaemoglobin
What are the types of blood vessel?
Arteries
Veins
Capillaries
