Lips and Tongue: Anatomy ( chorda tympani Chorda tympani A branch of the facial (7th cranial) nerve which passes through the middle ear and continues through the petrotympanic fissure. The blood supply of the tongue originates from the external carotid artery, and the innervation is through cranial nerves. Taste from anterior ⅔ of tongue Tongue The tongue, on the other hand, is a complex muscular structure that permits tasting and facilitates the process of mastication and communication.Jaw and Temporomandibular Joint: AnatomyĮye movement ( lateral rectus Lateral rectus Orbit and Extraocular Muscles: Anatomy muscle) Mastication Mastication The act and process of chewing and grinding food in the mouth.Nervous System: HistologyĮye movement ( superior oblique Superior oblique Orbit and Extraocular Muscles: Anatomy muscle) Motor Motor Neurons which send impulses peripherally to activate muscles or secretory cells. Accommodation Accommodation Refractive Errors.Sensory Sensory Neurons which conduct nerve impulses to the central nervous system. This pathway is composed of the olfactory cells and bulb, the tractus and striae olfactoriae, and the primary olfactory cortex and amygdala. From there, the olfactory nerve transmits the sensory perception of smell via the olfactory pathway. Olfaction: Anatomy ( smell Smell The sense of smell, or olfaction, begins in a small area on the roof of the nasal cavity, which is covered in specialized mucosa. ![]() ![]() Olfaction Olfaction The sense of smell, or olfaction, begins in a small area on the roof of the nasal cavity, which is covered in specialized mucosa. Table: Overview of the 12 cranial nerves (CNs) Nerve Nervous System: Anatomy, Structure, and Classification. The developed brain consists of cerebrum cerebellum and other structures in the brain stem. Arising from the neural tube, the embryonic brain is comprised of three major parts including prosencephalon (the forebrain) mesencephalon (the midbrain) and rhombencephalon (the hindbrain). The CNs are named and numbered in Roman numerals according to their location, from the front to the back of the brain Brain The part of central nervous system that is contained within the skull (cranium). Some CNs are involved in special senses, like vision Vision Ophthalmic Exam, hearing, and taste, and others are involved in muscle control of the face. Nervous System: Histology or motor Motor Neurons which send impulses peripherally to activate muscles or secretory cells. The CNs can be sensory Sensory Neurons which conduct nerve impulses to the central nervous system. Nervous System: Anatomy, Structure, and Classification to various parts of the head, neck Neck The part of a human or animal body connecting the head to the rest of the body. There are 12 pairs of cranial nerves (CNs), which run from the brain Brain The part of central nervous system that is contained within the skull (cranium).
