Uncinate

Uncinate process is a term used in anatomy for a number of structures that have a hook-like shape. The term comes from Latin uncinatus, meaning "hooked".

Uncinate process of ethmoid bone

The ethmoid bone is a singular porous bone that makes up the middle area of the viscerocranium and forms the midfacial region of the skull. It contributes to the eye socket, nasal cavity, and nasal septum. The uncinate process of the ethmoid bone is a thin, curved process that extends downward and backward from this bone. It forms a part of the medial wall of the ethmoidal infundibulum, which is a funnel-shaped opening in the ethmoid bone.

Uncinate process of pancreas

The pancreas is a gland organ in the digestive and endocrine system of vertebrates. It is both an endocrine gland producing several important hormones, including insulin, glucagon, and somatostatin, as well as a digestive organ, secreting pancreatic juice containing digestive enzymes that assist the absorption of nutrients and the digestion in the small intestine. The uncinate process of the pancreas is a part of the pancreas that extends from the lower part of the head of the pancreas. It lies deep to the superior mesenteric vein.

Uncinate process of vertebra

The vertebra are the individual bones that stack up to make the vertebral column (spine). The uncinate process of the vertebra is a hook-shaped process on the lateral edges of the superior surface of the bodies of the third to the seventh cervical vertebrae and first thoracic vertebra. They limit lateral flexion and act as a joint surface for the vertebra above.
