Mylohyoid Nerve

By | 2018-03-26T09:43:09+00:00 March 26th, 2018|Anatomy, Head and Neck, Nerves|

The mylohyoid nerve a.k.a. nerve towards mylohyoid is a division of the inferior alveolar nerve, which itself is a branch of the mandibular division of the trigeminal nerve. Mylohyoid Nerve Origin The mylohyoid nerve generally arises via the inferior alveolar nerve approximately 14 mm superior towards the mandibular foramen. Sometimes, the mylohyoid nerve [...]

The lingual nerve is a sensory division belonging to the posterior branch of the mandibular division of the trigeminal nerve. Lingual Nerve Origin The lingual nerve arises via posterior division of the mandibular nerve and travels down in the middle of the ramus of the mandible as well as the medial pterygoid muscle. [...]

Inferior Alveolar Nerve

By | 2018-03-12T07:27:25+00:00 March 12th, 2018|Anatomy, Head and Neck, Nerves|

The inferior alveolar nerve a.k.a. the inferior dental nerve is a division of the mandibular nerve, the third division of the trigeminal nerve. The inferior alveolar nerve is primarily a twin motor and sensory nerve. It innervates the lower teeth. It is also the largest branch of the mandibular nerve. Inferior Alveolar Nerve [...]

Ventral Rami

By | 2018-02-01T06:49:45+00:00 January 19th, 2018|Anatomy, Head and Neck, Nerves|

31 pairs of spinal nerves are found in the human body. All spinal nerves originate through a ventral root and a dorsal root. Note that in the human anatomy, anterior and posterior are correspondingly equivalent of ventral and dorsal. All roots are formed by the combination of many dorsal and ventral root filaments or rootlets. [...]

By | 2018-02-01T07:47:30+00:00 January 12th, 2018|Anatomy, Head and Neck, Nerves|

Origin The transverse cervical nerve is a division of the cervical plexus originating from the anterior rami of cervical nerves C2 and C3. The transverse cervical nerve is otherwise known as the Superficial cervical nerve Cutaneous cervical nerve Anterior cutaneous cervical nerve of the neck Transverse cervical nerve Insertion It appears from under [...]

Supraclavicular Nerves

By | 2018-02-01T07:49:31+00:00 January 12th, 2018|Anatomy, Head and Neck, Nerves|

The supraclavicular nerves is a name referred to a group of cutaneous nerves originating via cervical nerves C3 and C4 that travel downwards and stimulate the skin over the clavicle and shoulder inferiorly till the second rib after arising under the posterior margin of the sternocleidomastoid muscle. Origin The supraclavicular nerves start from the third [...]

Maxillary Nerve

By | 2018-02-01T07:49:53+00:00 January 12th, 2018|Anatomy, Head and Neck, Nerves|

The maxillary division of the trigeminal nerve, a.k.a. the maxillary nerve is a purely sensory nerve. It is the medium-sized branch of the trigeminal nerve in the middle of the smaller ophthalmic division as well as the biggest mandibular division. Maxillary Nerve Insertion It arises from the convex anterior border of the trigeminal [...]

Great Auricular Nerve

By | 2018-02-01T08:38:06+00:00 January 10th, 2018|Anatomy, Head and Neck, Nerves|

The great auricular nerve is a branch of the cervical plexus. It originates from the anterior rami of the C2 as well as C3 spinal nerves rises upwards on the surface of the sternocleidomastoid muscle. Great Auricular Nerve Insertion From the posterior margin of the sternomastoid the great auricular nerve turns and on [...]

Third Occipital Nerve

By | 2018-02-01T08:39:01+00:00 January 9th, 2018|Anatomy, Head and Neck, Nerves|

The C3 spinal nerve splits into an anterior ramus along with a posterior ramus. The posterior ramus divides into two medial branches and a lateral branch. The larger, superior medial branch is the third occipital nerve. From superior branch fibers of the third cervical nerve the third occipital nerve emerges at the level of the [...]

Zygomaticotemporal Nerve

By | 2018-02-01T08:40:25+00:00 January 8th, 2018|Anatomy, Head and Neck, Nerves|

The zygomaticotemporal nerve arises from a foramen located on the anterior wall of the temporal fossa. This foramen is located at the back of the lateral orbital rim, posterior towards the zygoma at the plane of the lateral canthus. Zygomaticotemporal Nerve Insertion The zygomaticotemporal nerve travels with the lower outer part of the [...]
