Micellaneous stuff i forget Flashcards
Anterior Fontanelle (allows for deformation of the head during childbirth)
Bregma
Sternocleidomastoid
- innervated by accessory nerve
- rotates head and neck.
Atlanto-occipital joint
- Synovial joint
- Articulation between C1 and occipital bone
- Up and down movement
Atlanto-axial joint
- Synovial joint
- Cruciate ligaments hold together
- Side to side movement of head.
Vertebral Canal
- space which Spinal cord passed through vertebral column
Foramen Transverarium
for vertebral arteries and veins
Annulus fibrosis
- Tough fibrocartilaginous rim
- Limits vertebral roatation
Nucleus pulposus
collagen fibres suspended in mucoprotein gel
- Absorbs compressive forces.
Kyphosis (dorsal convex)
primary curvature as present in the embryo
Lordosis (dorsal concave)
- secondary curvature (think sticking arse out)
Ligaments of the elbow
- Radial and ulna collateral ligaments
- Annular ligament between ulna and radius
Cubital fossa
- lateral border= brachioradialis
- medial border= pronator teres
- superior border= imaginery lines between epicondyles
Contents of cubital Fossa
- Really Need Beer To Be At My Nicest
- Radial nerve
Biceps tendon
Brachial artery
Median nerve
Posterior forearm muscles
SUPERFICIAL
- Extensor digiti minimi
- Anconeus
- Brioradials
Deep
- Extensor incidis
Vascular blood supply
- Aorta
- Brachiocephallic
- Left subclavian
Axillary
Brachial
Ulnar and radial
Collagen synthesis
- three hydroxylated and glycosylated propetides form triple helical procollagen
- leaves cell membrane
- Cleavage of N and C terminal propeptides
- Cross linking between collagen fibrils formas a collagen fibre
- Stabilised with pyridinium cross links
Role of Sex hormones in bones
- Increases osteoblast activity and synthesis of bone
Which type of cartilage lacks a perichondrium?
Fibrocartilage- prominently cartilage type 1
Vitamin a
osteoblast stimulation
Function of IGF
- secreted by liver and bones
- stimulates osteoblasts and increases bone protein synthesis.
Function of Ihh
essential for columnar chondrocyte differentiation in growth plate
Function of PTHrP
reinforces chrondrocyte differentiation in bone development
Superficial glutes
Gluteus maximus= extension and lateral rotation of hip
Gluteus minimus= abduction and medial rotation of hip
Deep gluteal muscles
Gemellus superior/infeior
Obturator internus/externus
piriformis
Quadratus femoris
- all laterally rotate hip
