Spaces Anatomy Flashcards
Which space is surrounded
»_space;» medially -by the geniohyoid and genioglossus muscles
»_space;»posteriorly -by the hyoid bone
Sublingual space
Which space contain
> > > the submandibular duc (Wharton’s duct)
the lingual and hypoglossal nerve
terminal branches of the lingual artery
part of the submandibular gland
Sublingual
What’s medial and posterior boundaries of submandibular space ?
> > > Medially- by the anterior belly of the digastric muscle
posteriorly- by the stylohyoid ligament and the posterior belly of the digastric muscle
What’s anterior and posterior boundaries of Pterygomandibular space ?
> > > anteriorly- by the pterygomandibular raphe / posteriorly -by the parotid gland
−supereior is infraorbital margin
− lower is an alveolar process of maxilla,
− internal is an edge of the pear-shaped aperture,
− external is zygomatico-maxillary suture.
Which space ?
Canine space
What’s superior and inferior boundaries of buccal space ?
Superior – Zygomatic process of maxilla, lower edge of zygomatic bone
Inferior - lower edge of mandible
Anterior- a line connecting zygomatico-maxillar suture with sutures of the corner of the mouth
Posterior - anterior border of the masseter muscle
Guess the space ?
Buccal space
What’s medial and lateral boundaries of buccal space ?
> > > Medial- buccinator muscle / Lateral- skin,subcutaneous tissue and platysma
Superficial temporal space boundaries?
laterally by the temporal fascia
medially by the temporalis muscle,
Deep temporal space boundaries ?
between the medial surface of the temporalis muscle and the temporal bone
Which space continue with inftratemporal?
Temporal space
Espicially the deep
the superior extension of the pterygomandibular space ( foramen spinum and round )
Laterally, this space is bounded by the ramus of the mandible and the temporalis muscle
medially, it is bounded by themedial and lateral pterygoid muscles, and is continuous with the temporal fossa.
Infratemporal space
What’s superior , inferior , anterior , posterior, medial , lateral submasseteric space boundaries ?
Superiorly - zygomatic arch
Inferiorly - masseteric muscle attachmnt on the mandible
Anteriorly - anterior border of masseteric muscle
Posteriorly - parotid gland and posterior aspect of masseter muscle
Medially - lateral aspect of ramus of mandible
Lateraly - medial surface of the masseter muscle
What’s superior , lateral , inferior boundaries of submental space ?
> > > Superiorly - by the mylohyoid muscle
laterally and on both sides - by the anterior belly of the digastric muscle
Inferiorly - by the superficial layer of the deep cervical fascia, by the platysma muscle and overlying skin.
anterior jugular vein and the submental lymph nodes. In which pace ?
Submental
