Teaching slides for session: Duodenum and Spleen
Summary
This engaging on-demand teaching session for medical professionals dives deep into a detailed anatomy revision covering the structure and functioning of the abdominal wall and foregut. Particularly focusing on two central aspects of the session - the spleen and the duodenum, the different anatomical facets, including positions, blood supply, relationships with other abdominal organs, and peritoneal attachments, will be thoroughly explained. Attendees will gain insights into the intricate structure of the duodenum, its common ulceration site, and different parts. They will also learn about the spleen's position against the diaphragm, its connections, and blood supply. Moreover, the session will also examine the peritoneal attachments and their role. Come join this medical session to solidify and enhance your anatomical knowledge.
Learning objectives
-
By the end of this session, participants will be able to accurately describe the functional anatomy of the duodenum, including its position, parts, secondary retroperitoneal attachment and relations to other abdominal organs.
-
Participants will be able to detail the anatomy of the spleen, specifically its position, blood supply, relations and peritoneal attachments.
-
Attendees will be able to identify and describe the structure and function of the major and minor duodenal papillae.
-
Participants will have a clear understanding of the peritoneal attachments both for the duodenum and spleen, and the distinction between intra and retroperitoneal organs.
-
