ENDOCRINE Endocrine glands have no ducts They secrete into the blood from where the secretion (hormone) reaches a target cell The following is a list of endocrine glands: Hypophysis Thyroid Parathyroid Adrenals Islets of Langerhans Pineal Gonads Hypophysis: Develops from oral ectoderm and nerve tissue,  The oral part forms an upgrowth with an invagination (Rathke's pouch) The nervous part grows from the floor of the diencepha…

Bones begin to form during the eighth week of embryomic life in the fibrous membranes (intramembranous ossification) and hyaline cartilage (endochondral ossification)

Innervation of the Pharynx The motor and most of the sensory supply of the pharynx is derived from the pharyngeal plexus of nerves on the surface of the pharynx. The plexus is formed by pharyngeal branches of the vagus (CN X) and glossopharyngeal (CN IX) nerves, and by sympathetic branches for the superior cervical ganglion. The motor fibres in the pharyngeal plexus are derived from the cranial root of accessory nerve (CN XI), and are carried by the…

The Parotid Glands The parotid glands are the largest of the three pairs of salivary glands. Each gland is wedged between the mandible and the sternocleidomastoid muscle and partly covers them. The parotid gland is wrapped with a fibrous capsule (parotid fascia) that is continuous with the deep investing fascia of the neck. Viewed superficially, the parotid gland is somewhat triangular in shape. Its apex is posterior to the angle of the ma…
