Pelvic Girdle - HIP BONE - Os coxae
Synarthrosis Pelvic Girdle - HIP BONE - Os coxae The pelvic girdle connects the spine with the hindlimb. It consists of two hip bones. They are attached to the sacrum posteriorly, fused with each other ventraly, and joined with the two femurs at the hip joints. The hip bone also consists of fusion between 3 main bones; Os ilium Os pubis Os ischii Coto

PELVIS Coto Synarthrosis
Pelvis (bony pelvis) consists of two hip bones (os coxae), sacrum and first few caudal vertebras It encloses the pelvic cavity. It is the section of the body caudal the abdomen. The reproductive organs (sex organs), some parts of urinary system and last part of digestive canal (the rectum) located in this gap Pelvic inlet (Apertura pelvis cranialis) Pelvic outlet (Apertura pelvis caudalis) Coto

FEMUR Thighbone Os femoris
Femur is the most proximal bone of the hindlimb. It is analagous to the humerus of upperarm It is the longest and strongest bone of the body It forms hip joint and stifle joint (knee joint) The Proximal and the distal extremities The body Coto
15
Femur : Proximal extremity

Patella – The Kneecap Coto The largest sesamoid bone in the body
It is soft cartilage in birth, ossified in childhood It covers and protects the knee joint It helps the extension of the knee Basis patella – m.quadriceps femoris attaches Apex patella – patellar ligament attaches Facies articularis and Facies cranialis Coto
20
OSSA CRURIS Skeleton of the leg, like that of the antebrachium, is formed by two long bones. Differently from that they can not rotate against one another, remain almost parallel. Fibula is the lateral bone of the crus. It is more slender Tibia is the medial bone of the crus. It is stouter Coto
21
FIBULA – The calfbone Coto
The fibula is located on the lateral side of the tibia, connected with it from above and below Caput fibulae Malleolus lateralis (Os malleolare in Ru) - The bone is fully-developed in Man, Su, Car. - The bone is reduced and distal half of it is absent in Equine. - The bone is rudimentary, the body is absent. The proximal end fuses with the tibia and distal end (os malleolare) articulates with the tibia in Ruminant. Coto
