Foramin Flashcards
(26 cards)
What is the passage for the mandibular division of the trigeminal nerve (CN V3)?
Foramen ovale
The foramen ovale allows passage of the mandibular division along with other structures.
What foramen allows passage for the maxillary division of the trigeminal nerve (CN V2)?
Foramen rotundum
The foramen rotundum transmits the maxillary division of the trigeminal nerve.
What structures are transmitted through the foramen that allows blood vessels and nerves to reach the orbit and face?
Superior orbital fissure and Inferior orbital fissure
These foramina are crucial for the passage of nerves and vessels to the facial region.
Which canal provides passage for the optic nerve and ophthalmic artery?
Optic canal
The optic canal is essential for the optic nerve and blood supply to the eye.
What foramina allow olfactory nerves to reach the nasal cavity?
Olfactory foramina
These foramina are responsible for the sense of smell.
What canal allows the hypoglossal nerve to innervate the muscles of the tongue?
Hypoglossal canal
The hypoglossal canal is important for tongue movement.
What is the external auditory meatus responsible for?
Protects and provides passage for structures of the ear
It helps maintain proper drainage of ear secretions.
What vessels and nerves does the foramen spinosum accommodate?
Middle meningeal vessels and meningeal branch of mandibular nerve (V3)
This foramen plays a role in the protection of the brain.
What is the function of the stylomastoid foramen?
Provides an exit point from the skull for facial nerve (CN VII)
It is crucial for facial nerve function.
What does the carotid canal allow to pass into the skull cavity?
Internal carotid artery
The carotid canal is essential for blood supply to the brain.
What structures are transmitted through the jugular foramen?
Glossopharyngeal, vagus, accessory nerves & jugular vein
This foramen is vital for cranial nerve function and venous drainage.
What is the function of the foramen magnum?
Allows the spinal cord to pass through from the brain to the vertebral canal
The foramen magnum connects the brain with the spinal column.
What is the function of choanae?
Allow air and mucus to pass from the nasal cavity into the throat
Choanae are important for respiratory function.
