Facial nerve
Trigeminal nerve
What blood vessels supply the face
Facial artery and neck
What are the two groups of muscles of the face And scalp
Muscles of facial expression
Muscles of mastication
What nerve innervates the muscle of facial expression
Cranial nerve 7
What nerve innervates the muscles of mastication
Trigeminal nerve
What are the 5 extra-cranial branches of then facial nerve
To Zanzibar By Motor Car
Temporal
Zygomatic
Buccal
Marginal mandibular
Cervical
What is the main sensory nerve of the face and scalp
Trigeminal nerve
What are the three key branches of the trigeminal nerve
Va- opthalmic division
Vb - maxillary division
Vc - mandibular division sensory and motor
What are the 3 branches of the aorta
Brachiocephalic
Left common carotid
Subclavian
What nerve innervates the platysma
Facial nerve
What nerve innervates the right SCM
Accessory nerve
What nerve innervates the trapezius
Accessory nerve
What muscles are up the Anatomical borders of the neck
SCM
Trapezius
What makes up the anterior triangle
Midline of neck
Base- inferior margin of mandible
Anterior margin of SCM
What makes up the posterior triangle
Anterior margin of trapezius
Posterior margin of sternocleidomastoid
Clavicle
What is associated with the anterior triangle
Structures coursing between the head and thorax
What is associated with the posterior triangle
Structures coursing between the thorax/neck and upper limb
What is in the posterior triage
EJV
Scalenes
Brachial plexus
Subclavian vein and artery
Omohyoid
What does the neck consist of
Neck extends from the lower margin of the mandible to the suprastenal notch of the manubrium and upper border of the clavicle
What lies within the superficial cervical fascial layer
Loose connective largely containing adipose
What are the three deep cervical fascia from superficial to deep
Investing layer, pre tracheal layer and pre vertebral layer
What is thes carotid sheath
Tubular, fibrous structure that extends from the base of the skull through the root of the neck to the arch of aorta
What is the retropharangeal space
One deep neck space
How cab you tell if the pathology is in the thyroid
Asking them to swallow and observing whether it moves, can help localise pathology to the thyroid gland
what do the muscles of mastication allow
act in the mandible to allow chewing
name the muscles of mastication
temporalis
masseter
two pterygoids
function of muscles of mastication except one
elevate the mandible
the except is lateral pterygoid
which muscles depress the mandible
suprahyoids- above the hyoid bone
what does the lateral pterygoid do
depress mandible- laaa
