30 Οκτ 2023 · The most important arteries and nerves of the head and neck are the following: Internal and external carotid arteries; Vertebral arteries; Thyrocervical trunk; Cranial nerves; Cervical plexus; Head and cervical lymph nodes; In this page, we’re going to study each of the above structures together with their respective branches.
30 Οκτ 2023 · Nerves of the head. Since the head is such a ‘vast’ anatomical region, it’s innervation is quite extensive. For the purposes of this page, we’ll only talk about the relevant nerves for the previously mentioned anatomical structures. The nerves in the head originate from three main sources: Trigeminal nerve (CN V) Facial nerve (CN VII)
The Head. Nerves of the Head. The nerves of the head include the sympathetic and parasympathetic innervation to the head and neck, as well as the three branches of the trigeminal nerve: ophthalmic, maxillary and mandibular. The sympathetic innervation begins in the spinal cord.
Structure. Bones. The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
