Which vertebra really sticks out of the back of the neck
Vertebra C7
Appendicular vs Axial Skeleton
Transverse Ligament

Tracheostomy (Between 2nd and 3rd Tracheal rings) is more long-term and done in an OR
Cricothyroidotomy (through cricothyroid membrane) is usually for emergencies

Compare superficiality and depth of arteries vs veins
Arteries are usually deeper while veins can be superficial or deep
Arteries in the neck
Common Carotid
Internal Carotid
External Carotid
Vertebral Artery
Branch of subclavian artery
The artery that goes through the vertebrae
External Carotid Artery
Provides vasculature for outside of head - that artery on your temples
Internal Carotid Artery
Provides arteries for your brain
Thyrocervical Trunk
Supplies the thyroid and up to the cervical part of the neck
Origin of Internal Thoracic Artery
Subclavian Artery
Sternocleidomastoid
When is the subclavian artery renamed to become the axillary artery
Lateral border of the first rib
What does the brachiocephalic vein form
SVC
Veins of the neck
Internal Jugular Vein
External Jugular Vein
Anterior Jugular Vein
Internal Jugular Vein
The big fat vein that goes alongside the inside of the neck
External Jugular Vein
The thinner vein that is more lateral to the neck
Drains into subclavian vein
Anterior Jugular Vein
Right at the front
X: Vertebral Vein
Y: Subclavian Vein
Brachial Plexus Nerves
Nerves in the shoulder that carries movement and sensory signals from the spinal cord to the arms and hands
