See muscle tables

18
Q

Boundaries of anterior triangle

A
19
Q

Label the superficial veins
Where do facial and retromandibular veins drain?
Where does the anterior vein drain?

A

retromandibular vein divides into two branches:
Anterior: joins the (anterior) facial vein, forming the common facial vein which drains into the internal jugular vein.
Posterior: joins the posterior auricular vein, forming the external jugular vein

Anterior drains into EJV or subclavian directly

20
Q

Retromandibular vein p521
— Formed by which two veins?
— Divides into?
— Those join with which veins and dump into ?

A

— Formed by which two veins? superficial temporal & maxillary v
— Divides into? anterior and posterior
— Those join with which veins and dump into ?
anterior + facial > IJV
posterior + posterior auricular > EJV

24
Q

Ansa cervicalis
Superior root is?

Supplies which group of muscles?

A

Superior root is? C1
Inferior roots are? C2, C3
Supplies which group of muscles? Infrahyoid

25

A
34
Q

Carotid triangle — which nerves, arteries, veins?
537

A

Nerves : X, XI and XII and Ansa cervicalis
All carotid arteries
IJV

35
Q

Root of the neck

A
36
Q

Thyroid and parathyroid glands
P530

A
37
Q

Blood supply & venous supply
Discuss their origins, branches, where they drain etc
536

A

External and internal carotid arteries arise from the common

left common carotid arises directly from the aortic arch

right common carotid arises from the brachiocephalic trunk

inferior thyroid vein drains into the brachiocephalic vein

middle & superior thyroid vein drain into the IJV

IJV drains into the brachiocephalic vein and then into the right atrium

A

Vertebral artery arises from the subclavain artery before the thyrocervical trunk p.583
Vertebral vein drains into the brachiocephalic vein
