Define articular cartilage

A

Connective tissue secures this to its external surface. Smooth slippery surface that decreases friction at joint.

162
Q

Define endosteum

A

Membrane lining the cavity of long bones

163
Q

Define metaphysis

A

Part between the shaft and end of long bone

164
Q

Define medullary cavity

A

Core of long bone containing the marrow. Sponges bone.

165
Q

Define osteoblasts

A

Build bone. Produce protein matrix. New bone forms.

166
Q

Three common fractures

A

Greenstick, compression and comminuted

167
Q

What happens in the process of the formation of haematoma?

A

Blood vessels are ruptured when the bone breaks. Swelling.

168
Q

What is the process of fibrocartilage/soft callus in repair of bone fracture

A

Growth of new capillaries into clotted blood at the site of damage. Connective tissues form a mass to act as a splint and close the gap

169
Q

What happens when a bony callus is formed in bone fracture?

A

Osteoblasts and osteoclasts migrate to the area and multiply replacing the fibro cartilage callous with a bony callous made of spongy bone

170
Q

Process of bone remodelling:

A

The bony callous is remodelled in response to stresses placed on it. A strong, permanent patch is formed on the fracture site.

171
Q

What are fibrous joints?

A

Bones are united by fibrous tissue. E.g. skull structures. Most are immobile but Some are slightly mobile.

172
Q

What are cartilaginous joints?

A

Slightly movable joints with bone ends connected by fibro cartilage. E.g. joints of spinal column.

173
Q

What are synovial joints?

A

Bone ends are separated by a joint cavity containing synovial fluid. Freely movable.

174
Q

What is the joint capsule?

A

Surrounds and reinforces the joint. Consists of a fibrous capsule and synovial membrane.

175
Q

What is the ligament in a synovial joint?

A

Fibrous tissue extending from bone to bone at the joint

176
Q

In a synovial joint, what is articular cartilage?

A

Covers the ends of the bones forming the joint

177
Q

In a synovial joint what is joint space?

A

Forms the synovial membrane secretive synovial fluid which lubricates the joint.

178
Q

Synovial joints allow four types of movement, what are they?

A

Rotation, angular, gliding, special movement.

179
Q

What is a synapse?

A

The gap between cells.

180
Q

What is the role of the neurotransmitter in muscular movement?

A

They assist electrical signals across the synapse

181
Q

What happens during action potential?

A

ACH diffuses across the synaptic cleft attaching to receptors in the post synaptic cell

Cell membrane permeability changes and a signal called action potential is generated.

NA+ ions leave the external fluid compartment and the internal fluid compartment. K+ ions leave the ICF and enter the ECF

182
Q

How does calcium influence action potential?

A

Ca+ ions ensure contraction and relaxation of a muscle cell.

183
Q

What returns the muscle cell to its resting state?

A

When ca+ decreases, tripping returns to its normal structure. Tropomyosin blocks the sliding action and movement is stopped - muscle relaxes

184
Q

How do skeletal muscle make movement?

A

Converts energy to a force. Contraction of muscles.

185
Q

How do skeletal muscle maintain posture?

A

Contractions of skeletal muscle maintain posture.

186
Q

How do skeletal muscles stabilise joints?

A

Limits movement in a joint and provide balance to the joint

187
Q

How do skeletal muscle generate heat?

A

Shivering when cold. (Negative feedback)

188
Q

Define excitability, contractility, extensibility.

A

Excitability is the rapid response to stimuli.

Contractility is the shortening in response to suitable stimuli

Extensibility is the capability of being stretched.

189
Q

Where would you find smooth muscle and what does it do?

A

Bladder – holds and releases urine
Blood vessels – pushing blood
Uterus – birth
Gastrointestinal tract – assists in digestion

190
Q

What does NSAID stand for?

A

Non steroidal anti inflammatory propionic acid derivative.

191
Q

What is ibuprofens mode of action?

A

Cyclo oxygenase (cox) inhibitor. Also acts on pain receptors. Prostiglandis.

192
Q

In handling what does STS stand for?

A

Stop, think, stability.

193
Q

what does L I TE stand for?

A

Load, individual, task, environment.

194
Q

What is the maximum Weight limit for men and women?

A

Women – 16.6 KG

Men – 25kg

195
Q

Is calcium homeostasis positive or negative feedback? What hormones are required?

A

Negative. Parathyroid hormone and the active form of vitamin D.

196
Q

Osteocytes

A

Arise from osteoblasts and care for and nourish the bone

197
Q

Osteoclasts

A

Break down bone that is damaged. Release Ca and Ph into blood for recycling
