General Anatomy Flashcards
Floor of suboccipital triangle:
Contents:
Muscle innervation:
- posterior arch of C1
- 3rd part of the vertebral artery
- dorsal Ramos of C1
Submandibular triangle:
Aka?
Contents?
- digastric triangle
- submandibular gland
Carotid Triangle contents:
carotid sheath containing:
- common carotid artery
- internal carotid artery
- internal jugular vein and CN X
Submental triangle:
Aka?
Floor?
- suprahyoid triangle
- mylohyoid muscles
Muscular triangle contents:
Thyroid
Trunks of the brachial plexus and CN XI run thru which anatomical triangle?
Posterior cervical triangle
Inguinal Triangle (of Hesselbach)/Hesselbach's Triangle: Floor? What passes thru?
-transversalis fascia
-direct hernias pass thru
[**indirect hernias pass thru the deep inguinal ring-a defect in the transversalis fascia]
Femoral Triangle (of Scarpa)/Scarpa's triangle: Contents?
-femoral nerve
-femoral artery
-femoral vein
-femoral canal
[**artery, vein and canal lie inside the femoral sheath; femoral nerve lies outside of the femoral sheath]
Thoracic Outlet:
Aka?
Superior thoracic aperture
Axilla contents:
(-axillary artery and branches, axillary vein and tributaries, cords of brachial plexus)
- and 6 groups of lymph nodes:
- Anterior (pectoral)
- Posterior (subscapular)
- Infraclavicular
- Central
- Apical
- Lateral (along the axillary vein)
Flexor Retinaculum=
1” fibrous Square attached to the following carpal bones:
S-scaphoid
T-trapezium
O-os hamate
P-pisiform bones
The ___ ___ of the Median Nerve passes over the retinaculum and therefore is NOT compressed, allowing for the sensation of the palm to be intact in carpal tunnel syndrome.
Superficial Palmar branch
Suboccipital triangle boundaries:
- obliquus Capitis superior
- obliquus Capitis inferior
- Rectus Capitis posterior major
