Chapter 1 Flashcards

Anatomical Position
Flexion of the wrist is movement that takes the hand forward from Anatomical Position

Flexion of the hip

Sagittal Plane (divides the body to left and right halves)
Forward/ Backward movement
Flexion/ Extension
(Lunges) Flexing/ Extending at Hip and Knee joint
(Bicep Curl) Flexion in the elbow joint

Flexion takes the body forward
Flexion of the hip

Sagittal Plane
Flexion of the shoulder

Sagittal Plane
Flexion of the hip

Sagittal Plane
Flexion (dorsiflexion) of the ankle

Sagittal Plane
Extension of the neck

Sagittal Plane
Extension of the shoulder

Sagittal Plane
Flexion of the knee

Sagittal Plane
Extension (plantarflexion)
of the ankle

Coronal/ Frontal Plane
Divides the body into anterior and posterior parts

Sagittal Plane

Frontal/ Coronal Plane
Movement side to side
Abduction/ Adduction
Lateral Flexion/ Extension

Transverse Plane
Rotational Movement
Lateral/ Medial
Right/ Left
Pronation/ Supination

Dorsiflexion - lifting the foot or hand in a direction that draws the fingers or toes closer to the body
Plantarflexion - movement of the foot in a downward motion away from the body

Frontal Plane
Abduction

Frontal Plane
Adduction

Frontal Plane
Lateral Flexion
Extension is moving back

Lateral Rotation

Medial Rotation
Multiple Functions of Bones
Rigid Support (compressive/ tensile (tension) forces)
Levers for muscle action

Nutrient Vessel
Compact Bone

Calcified Matrix
Growth circles (like trees) around central channel
which houses blood vessels/ nerves.
Nerves supply blood to the deeper spongy bone and living cells in compact bone.

Osteon
Funcitonal unit for bone.
2

Haversian Canal
Tubes in network of bone containing blood vessels.
3

Osteocyte
Oseoblasts trapped in surrounding bone tissue.
They communicate through canaliculi
Monitor the bone tissue and will produce new bone/ destroy damaged bone if activated by stress or damage to tissue around them.

Canaliculi
Hair like channels n haversian system.

Compact Bone
The inner layer of compact bone contains oseoblasts, cells that secrete collagen/ minderal salts that increase the bone’s resistance to breakage.
The outer layer of compact bone has blood vessels/ nerves weaving through canals into deeper spongy bone.

Spongy bone - porous, open spaces.
Spaces are filled with marrow and blood vessels.
Three types of cells work to repair damage and remodel bone are…

Osteoblasts - Live between periosteum/ compact bone producing new bone sythesizing collagen/ minerals/ calcium phosphate.
Osteoclasts - Resorption
Osteocytes - Formation
Which cell breaks down bone?
Osteoclasts
removes the damaged tissue
Which bone cell repair the area by producing more bone?
Osteoblasts
