Dental Embryology Terminology (Week 2)

TermDefinition
Pharyngeal Arch Also known as the branchial arch. The pharyngeal arch are tissues that bend around the sides of a pharynx in the shape of bars. Each arch is separated by grooves on the external aspects of the neck at the fifth week.
Pharyngeal Pouch The pharyngeal pouches are grooves that separate each pharyngeal arch. These pouches match the pharyngeal cleft on the external aspects of the neck. There are five total pouches: Pouch I, Pouch II, Pouch III, Pouch IV, Pouch V.
Pharyngeal Arch #1 Muscles Occurs around the sixth and seventh week. The muscles begin to become more evident and form the masseter, medial and lateral pterygoid, and temporalis muscles. All these muscles form the mandible.
Pharyngeal Arch #1 Nerves The nerves in pharyngeal arch #1 develop around the same time as the muscles in arch #1. At the end of the seventh week, the fibers of the fifth nerve have entered the mandibular muscle mass along with the seventh nerve in the facial mass.
Pharyngeal Arch #1 Cartilage/Bone Initial development of the skeletal aspect. This is where Meckel's cartilage appears bilaterally. The two cartilages approach each other at the midline and eventually develop into the malleus, incus, and stapes or the middle ear.
Pharyngeal Arch #1 Vessels Each arch contains a right and left aortic arch vessel that forms at the heart and extends to the face, brain, and posterior regions of the body. The vessels in arch #1 develop in the fourth week and disappear in the fifth week.
