Articular capsule of the knee joint Articular capsule of the knee joint The articular capsule of the knee joint (commonly referred to as capsular ligament) is wide and lax; thin in front and at the side; and contains the patella ("knee cap"), ligaments, menisci, and bursae. The capsule consists of a synovial and a fibrous membrane separated by fatty deposits anteriorly and posteriorly. Anteriorly, the reflection of the synovial membrane lies on the femur; located at some distance from the cartilage because of the presence of the suprapatellar bursa.

Tibia fusus cm (9 in.). These shells are large, spindle-shaped with moderately convex turns and an extremely long, thin and slightly curved siphonal canal. The basic color ranges from straw yellow to reddish-beige. The aperture is ovate and white inside, with 6 fingerlike growths on the outer lip. It is a fairly common species where it occurs, but because of its attractive appearance, it is highly sought after by shell collectors. Embryos develop into free-swimming planktonic marine larvae (trocophore) and later into juvenile veligers. Tibia fusus Tibia fusus, common name Spindle tibia or Shinbone Tibia Gastropod, is a species of large sea
