Anatomy and Revision Flashcards
what is a syndemoses
fibrous joint that unites bones with fibrous sheet fibrous membranes
what are fontanelles
wide sutures in the neonatal skull
what are synchondroses
primary cartilaginous joints joined by hyaline cartilage
what are the articular surfaces in synovial joints convered in
hyaline cartilage
what are the 5 types of synovial joints
pivot, ball and socket, plane, hinge, biaxial
least the joint types from least stable and most motile to most stable and least motile
synovial- cartilaginous- fibrous
what is a subluxation
reduced area of contact between articular surfaces
what is endochondral ossification
process in which hyaline cartilage grows and ossifies into bones
list the components of bones from top downwards
epiphysis epiphyseal growth plate metaphysis diaphysis metaphysis epiphyseal growth plate epiphysis
describe the structure of bones
outer cortex surrounding inner medulla (spongy and may contain bone marrow)
what is the periosteum
fibrous connective tissue ‘sleeve: that is well vascularised and innervated
where do the superficial lymphatic of the lower limb follow and drain to
follow saphenous veins, drain to superficial inguinal lymph nodes then external iliac lymph nodes
what is the path of the deep lymphatics of the lower limb
follow deep veins
popliteal lymph nodes
deep inguinal lymph nodes
external iliac lymph nodes
how does lymph travel from external to common iliac nodes
lumbar lymphatics
what does the femoral nerve innervate and what are its nerve root levels
L2,3,4 quadriceps femoris sartorius iliacus pectineus
what does the tibial part of the sciatic nerve innervate and what are its nerve root levels
L4-S3
posterior leg
- true hamstrings: semimembranous, semitendinosus, long head of biceps femoris
- gastrocneumius
- soleus
- plantaris
- popliteus
- tibialis posterior
muscles of sole of the foot
- flexores of digits (digitorum and hallucus longus)
- all intrinsic muscles of the sole of the foot
via what does the tibial part of the sciatic nerve innervate the intrinsic muscles of the sole of the foot
medial and lateral plantar branches
what does the obturator nerve innervate and what are its nerve root levels
L2,3,4
all of the medial compartment of the thigh
all abductors (except hamstring part of magnus) and gracilis
what does the common fibular part of sciatic nerve innervate and what are its nerve root levels
L4-S2
short head of biceps femoris
what does the superficial fibular branch of the common fibular nerve innervate
muscles of the lateral compartment of the leg;
- fibularis longus
- brevis
what does the deep fibular branch of the common fibular nerve innervate
muscles of the anterior compartment of the leg
-fibularis longus and brevis
muscles of the dorsum of the foot
- extensor digitorum brevis
- extensor hallucis brevis
what type of joint is the acromoclavicular
plane types
what type of joint is the glenohumeral
ball and socket
what type of joint is the elbow (humeroulnar and radiohumeral)
hinge
what type of joint is the proximal radioulnar joint
pivot
what type of joint is the radiocarpal
ellipsoid
what type of joint is the sternoclavicular
saddle
what limits the movement of the radiohumeral joints
is a ball and socket limited by the annular ligament
what is the only bone attachment of the upper limb to the axial skeleton
sternoclavicular joint
what happens to the bones in the forearm during pronation
radius moves over the ulna which remains still
what allows the pivot of the forearm during supination and pronation
annular ligament
what degree of rotation does the thumb have
90 degrees
what type of joint is the 1st CMC joint
saddle type
what type of joint is the 5th MCP
condyloid
describe a saddle joint
movement is almost all direction, more stable than a ball and socket
what movement is extension of the thumb
thumbs up
what movement is flexion of the thumb
back towards the fingers
what movement is abduction of the thumb
palm flat facing ceiling, thumb up to ceiling
what forms the carpal tunnel
flexor retinaculum, carpals
what is the deep fascia of the arm
brachial fascia
what is the deep fascia of the forearm
antebrachial fascia
what is the deep fascia of the leg
crural fascia
what is the deep fascia of the foot
plantar fascia
what is another name of the common fibular nerve
common peroneal
what nerve commonly causes foot frop
deep fibular
if lateral compartment involvement aswell think common fibular
ho can you increase bone mass
weight bearing exercise
body mass
where does the tensor fascia lata run between
ASIS and lateral thickening of IT band
what is the fascia lata
a fibrous sheath
what other conditions is sjogrens associated with
RA and lupus
what type of arthritis never affects the DIPs
RA
what is AAV
ANCA associated vasculitis
why in sjogrens in PV and ESR much higher than CRP
as increased immunoglobulins thicken the blood
why do patients with psoriasis or on chemo have increased risk of gout
as they have increased cell turnover
what is undifferentiated CTD
some features of CTD with some positive antibodies without specific CTD antibodies
why is the lateral collateral ligament smaller than the medial
as lateral side also has IT band crossing the knee (and hip) joint
where do the obturator and femoral nerves both originate from
L2,3,4 in lumbar spinal plexus
how do you check for a torn posterior cruciate ligament
look for posterior sag, then do posterior drawer
what should you do instead of the anterior drawer test to test ACL
