Abstract

This chapter aims to cover surgical anatomy of head, neck, and brain. Sutural joints are formed when bones are united by fibrous tissue; therefore, these are examples of fibrous joints. Scalp consists of five layers i.e. skin, connective tissue, aponeurosis, loose areolar tissue, and pericranium. Lacrimal apparatus consists of lacrimal gland, lacrimal ducts, conjunctival sac, lacrimal canaliculi, and lacrimal sac. Palatine tonsils are collection of lymphoid tissue situated on either side of oropharynx in-between palatoglossal arch in front and palatopharyngeal arch behind. The nasal septum is formed anteriorly by hyaline cartilage (the septal cartilage) and posteriorly by perpendicular plate of ethmoid and vomer. Taste buds are present in relation to circumvallate papillae, fungiform papillae and to leaf-like folds of mucosa (folia linguae) present on the posterolateral aspect of the tongue. Movement of temporomandibular joint, parotid gland, thyroid gland, orbital fissure, nasal cavity, filum terminale, corpus callosum, arachnoid granulations, etc. are the other important topics which are also covered briefly in this chapter.
