Endoneurium, perineurium, and epineurium
Study Notes
Anatomy of Blood Vessels and Lymphatic System
- Arterial wall consists of tunica intima, tunica media, and tunica externa
- Arteries include elastic and muscular types, with the aorta being the largest elastic artery
- Terminal vascular bed includes arterioles, capillaries, and venules for fluid exchange
- Veins have valves, and venous return is supported by various mechanisms
- Portal circulation involves two capillary beds in the digestive organs and liver
- Pulmonary circulation involves oxygenation of blood in the lungs
- Lymphatic system includes lymphatic organs and vessels for fluid and fat transport, and immune defense
- Lymphatic vascular system is formed by lymphatic capillaries, precollectors, collectors, and vessels
- Nervous system includes the central and peripheral nervous systems
- Peripheral nervous system consists of afferent and efferent nerve fibers, myelinated and unmyelinated fibers
- Peripheral nerve structure includes endoneurium, perineurium, and epineurium
- Key source: "General Anatomy and Musculoskeletal System (Thieme Atlas of Anatomy)" by Schuenke, Schulte, Schumacher, et al. (Thieme Publishers, 2021)
