from trunk of
mandibular nerve
Medial pterygoid
from anterior
division of mandibular nerve
1-Temporalis
2-Masseter
3-Lateral pterygoid
Contents of Temporal fossa
- Temporalis muscle
- Deep temporal nerve &
vessels - Middle temporal artery
- Superficial temporal vessels
Contents of Infratemporal Fossa
- Sphenomandibular ligament
- Lateral & medial pterygoid
muscles - Mandibular nerve & its
branches - A part of maxillary nerve
- Otic ganglion
- Chorda tympani
- Lesser petrosal N. (of
Glossopharyngeal N.) - Part of maxillary artery &
some of its branches - Pterygoid plexus of veins
Carries general sensations from anterior
2/3 of tongue
Lingual nerve
is the largest parasympathetic
ganglion of the head.
The pterygopalatine ganglion
It is called the artery of extra-dural hemorrhage.
Middle meningeal artery
The largest of the meningeal vessels and supplies much of the dura
mater and bone, of the cranial cavity.
Middle meningeal artery
Formed by union of posterior
auricular v & posterior division of retromandibular v
External jugular vein
Tributaries of external jugular vein:
1.Anterior jugular v
2.Transverse cervical v
3.Suprascapular v
4. Posterior external jugular
muscles they
stabilize the hyoid bone
to provide a base for the
movements of the
tongue.
They also participate in
the movements of the
larynx in swallowing.
Infrahyoid muscles
All infrahyoid muscles are supplied by ansa cervicalis except,
…………… by C1
Thyrohyoid
• Bleeding cause generalized swelling of scalp.
• Called dangerous layer of scalp, as emissary veins open here and carry any infections inside the brain.
• Bleeding in this layer lead to black eye.
Loose connective tissue
The differentiation and migration of the sclerotome requires induction from both the ………………. and …………….
neural tube & notochord
The only major structure that passes directly through the medial wall and into the axilla is the ………………………
Intercostobrachial nerve
Unsegmented parachordal mesenchyme forms the:
Basilar part of the occipital
Inter maxillary segment gives rise to:
1-Philtrum of the upper lip.
2-Premaxilla, which forms the part of the upper jaw.
3-Triangular primitive palate.
Flexor of elbow joint when forearm is midpronated is the the function of which muscle?
Brachioradialis
Emerges through mental foramen
as mental nerve supplying skin of
lower lip & chin
Inferior alveolar nerve
Inner surface of tympanic membrane innervated by ………………… & Outer surface of tympanic membrane innervated by ……………………
Tympanic branch of glossopharyngeal / Auricular branch of vagus
Gives motor fibers to sternomastoid & trapezius
Accessory nerve
