untitled deck Flashcards
Strontium ranelate
‘Dual action bone agent’ - increases deposition of new bone by osteoblasts and reduces the resorption of bone by osteoclasts
Osteomalacia
Low calcium and phosphate, High ALP
Ventricles draining order
Lateral ventricles -> interventricular foramen -> third ventricle -> cerebral aqueduct -> fourth ventricle -> central canal
ear parts
Ear: helix / tragus / concha / lobule
Median umbilical ligament
- remnant of the urachus (obliterated allantois)
Bone formation:
Chondrification (differentiation of mesenchyme into chondrocytes) and endochondral ossification
Constrictions of oesophagus:
Aortic arch
Bronchus
Cricopharyngeus muscle
Diaphragm hiatus
Thigh nerve supply:
Anterior compartment- femoral n
Posterior compartment - sciatic n
Medial compartment - obturator n
Urogenital system
develops from intermediate mesoderm and cloaca
Facial nerve branches
Temporal branch
Zygomatic branch
Buccal branch
Marginal mandibular branch
* Cervical branch
Leg nerve supply:
Anterior compartment - deep fibular
Lateral compartment - superficial fibular
Posterior compartment - tibial nerve
1st pharyngral arch
V (maxillary and ext carotid arteries)
2nd pharyngeal arch
VII (stapedial and hyoid arteries)
3rd pharyngeal arch
IX (common and internal carotid)
4th pharyngeal arch
X (subclavian a and aortic arch)
6th pharyngeal arch
X (pulmonary artery)
Paraurethral glands of Skene -
female counterpart of prostate
Müllerian duct -
becomes uterus and fallopian tubes
Wolffian duct -
becomes epidydymis and vascular deferens
Müllerian duct remnants in men :
testicular appendage, prostatic utricle
Bochdalek vs Morgagni -
both diaphragm hernias; bochdalek left posterior, morgagni right anterior
Exomphalos/omphalocoele vs gastroschisis
gastroschisis no membrane/sac, urgent repair but staged; exomphalos sac present and semi urgent
Exomphalos -
gut does not return to abdominal cavity
Gastroschisis
- abdominal wall fails to close
Prefixed brachial plexus -
C4 contributes to the plexus and T1 does not
Postfixed plexus -
T2 contributes to the plexus but C5 does not

6th pharyngeal arch:
Recurrent laryngeal n, intrinsic muscles of larynx
1st pharyngeal pouch:
Eustachian tube, middle ear
2nd pharyngeal pouch:
Palatine tonsils
3rd pharyngeal pouch:
Thymus and inferior parathyroid gland
4th pharyngeal pouch:
C cells of parathyroid, superior parathyroids
