Infundibulum

Infundibulum is a term used in anatomy to describe a funnel-shaped structure. It is used in various contexts within the human body, including the brain, the heart, and the reproductive system.

Brain

In the brain, the infundibulum refers to the stalk that connects the hypothalamus to the pituitary gland. This structure is also known as the pituitary stalk. It is responsible for transporting hormones from the hypothalamus to the pituitary gland.

Heart

In the heart, the infundibulum refers to the conus arteriosus, a conical pouch formed from the upper and left angle of the right ventricle in the chordate heart, from which the pulmonary trunk arises.

Reproductive system

In the female reproductive system, the infundibulum is the funnel-shaped opening into the Fallopian tube near the ovary. It is lined with cilia which help to move the ovum from the ovary into the tube.
