Antrum

Antrum

An antrum is a cavity or chamber, particularly one found in the body. In anatomy, the term "antrum" is commonly used to refer to several specific structures in the human body.

Gastric Antrum

The gastric antrum is a region of the stomach located near the pyloric sphincter. It is responsible for mixing food with gastric juices and regulating the flow of partially digested food into the small intestine. The gastric antrum plays a crucial role in the digestive process by breaking down food particles and preparing them for further digestion and absorption.

Maxillary Sinus

The maxillary sinus, also known as the antrum of Highmore, is the largest of the paranasal sinuses located in the maxillary bone of the skull. The maxillary sinus plays a role in humidifying and filtering air, as well as lightening the weight of the skull. It is also involved in the resonance of the voice.

Mastoid Antrum

The mastoid antrum is a cavity within the mastoid process of the temporal bone. It connects to the middle ear and serves as a pathway for the drainage of fluid and maintenance of air pressure within the ear. The mastoid antrum is important for the health and function of the middle ear.

Ethmoidal Cells

The ethmoidal cells, also known as ethmoidal air cells or ethmoid sinuses, are a group of small air-filled cavities located within the ethmoid bone of the skull. These cells play a role in humidifying and filtering air, as well as contributing to the structural integrity of the skull. The ethmoidal cells are interconnected and drain into the nasal cavity.
