What does Branchiomotor mean?
What does Branchiomotor mean?
(brang’kē-ō-mō’tēr), Relating to or controlling the movement of muscles associated with the pharyngeal (branchial) arches.
What is the pharyngeal arch?
The pharyngeal arches, also known as visceral arches, are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches. In fish, the branchial arches support the gills.
Which branch of trigeminal nerve has Branchiomotor fibers?
Facial nerve (cranial nerve VII) The facial nerve proper (containing branchiomotor or special visceral efferents) supplies the muscles of facial expression, stapedius (small muscle in middle ear), stylohyoid, and the posterior belly of the digastric.
What is the Branchial motor function?
Branchial motor (special visceral efferent) neurons. Innervate skeletal muscles derived from the branchial arches, including the muscles of mastication and facial expression and the palatal, pharyngeal, laryngeal, trapezius and sternocleidomastoid muscles.
Is Trochlear sensory or motor?
Table of cranial nerves
| No. | Name | Sensory, motor, or both |
|---|---|---|
| II | Optic | Sensory |
| III | Oculomotor | Mainly motor |
| IV | Trochlear | Motor |
| V | Trigeminal | Both sensory and motor |
What are the three branches of the trigeminal nerve?
It contains the sensory cell bodies of the 3 branches of the trigeminal nerve (the ophthalmic, mandibular, and maxillary divisions). The ophthalmic and maxillary nerves are purely sensory.
How do you test facial nerves?
Testing the facial nerve involves the assessment of the muscles of facial expression:
- Initially assess for symmetry in the face at rest.
- Ask the patient to perform the following movements. Raise their eyebrows. Close their eyes tightly. Blow out their cheeks. Smile.
Can facial nerves repair themselves?
Facial nerve repair is infrequently required, because most of these patients regain function spontaneously. When paralysis is permanent, some advocate facial nerve decompression in selected cases.
