Osteology of ULNA

The ulna is a long bone in the forearm. It lies medially and parallel to the radius, the second of the forearm bones. The ulna acts as the stabilizing bone, with the radius pivoting to produce movement. Proximally, the ulna articulates with the humerus at the elbow joint. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint. #ulna #healthcare #anatomy #mbbs #medicalstudent #medicine #osteology #bones

Osteology of Patella - MBBS 1st year

Its superior aspect is attached to the quadriceps tendon and inferior aspect to the patellar ligament. ๐Ÿ‘‰It is classified as a sesamoid type bone due to its position within the quadriceps tendon, and is the largest sesamoid bone in the body. In this article we will look at the anatomy of the patella – its surface features, functions and clinical relevance. Patella Osteology of Patella Bony Landmarks: --------------------- ๐Ÿ‘‰The patella has a triangular shape, with anterior and posterior surfaces. The apex of the patella is situated inferiorly and is connected to the tibial tuberosity by the patellar ligament. The base forms the superior aspect of the bone and provides the attachment area for the quadriceps tendon. ๐Ÿ‘‰The posterior surface of the patella articulates with the femur, and is marked by two facets: Medial facet – articulates with the medial condyle of the femur.
