Anatomy and Physiology of the Hip and Knee

Hip (or "multi-jointing hip") refers generally to any joint, including ligaments and muscles, in the body which moves in a forward and/or backward direction with some degree of flexibility.hip pads manufacturers The hip joint was first identified by Jean Piaget's five senses as an anatomic area that included the head, neck, spine, hips, thighs, and pelvis.hip pads manufacturers hip pads manufacturers The hip joint was further divided into two areas, the inner hip joint, which were the origin of the muscles, tendons, nerves, and blood vessels that comprise the hip, and the outer hip joint, which were the source of movement for the most of the movements involved in walking, running, jumping, and cycling. Although Piaget noted the similarities between the head, neck, spine, pelvis, and hip in his model of human anatomy, he did not consider the hip to be part of this model. As a result, a variety of disorders affecting the hip were excluded from the definition of this particular area of human anatomy.

In vertebrate anatomy, hip (or "multi-jointing hip") refers to any joint, including ligaments, muscles, and tendons, that moves in a forward and/or backward direction with some degree of flexion or rotation.hip pads manufacturers hip pads manufacturers An example of a single joint of this type in the body would be the gluteus maxiceps, the major muscle group in the lower region of the hips.hip pads manufacturers hip pads manufacturers Another example of a multi-jointing joint in this area would be the hamstring tendon, which inserts on the outside of the quadriceps femur into the hamstring muscle group.

Two groups of muscles are known to exist within the hip area: the hamstrings, which are located at the back of the thigh, and the quadriceps, which are located inside the hip joint and run from the pelvis to the shinbone.hip pads manufacturers hip pads manufacturers When one of these large muscles becomes stretched out beyond its ability to cope with the increased demands of exercise, it can cause pain.hip pads manufacturers hip pads manufacturers The hamstrings are the muscles responsible for a great deal of the power output, a person can exert through their movements. If these muscles become overstressed or injured, it is likely that an individual will experience a great amount of pain in their lower region of the body. Conversely, the quadriceps muscles control the power output through the leg. If they become strained or injured, it is likely that an individual will experience a reduction in their overall physical function.

The terms of art used to describe the location of a bone and the location of a femoral head are called tibial cartilage and femoral head.hip pads manufacturers hip pads manufacturers A bone is defined as a hard mass of tissue found in animals and humans.hip pads manufacturers Examples of hard bones include the ribs, teeth, claws, bones, and so forth. The location of a femoral head is termed as femoral head or sacrum. This refers to a piece of soft tissue that originates in the lower part of the thigh bone and extends along the outer edges of both leg and hip joints. There exists a sacbral ligament that connects this piece of tissue to the inner surface of the tibia and shinbone.

The term of art referred to a structure that lies between a hip and femur.hip pads manufacturers hip pads manufacturers The articular structures that lie between these two pelvic structures are called the trochanters.hip pads manufacturers The trochanters allow for the free movement of hip joints and are therefore considered to be important when discussing the function of the hips. The tibial artery and its branches that extend to the inner parts of both legs and outside of the thigh are the major components of the femoral artery. The femoral artery originates from the anterior lumbar region and extends to the sacrum in a side to side motion.

The four quadriceps muscles are the greatest contribution to one's overall posture and movement.hip pads manufacturers hip pads manufacturers The primary muscle responsible for maintaining one's upright posture is called the extensor tendon and has a pronounced involvement in hip joint movements.hip pads manufacturers The second muscle, which is the semitendinosus, originates in the hip abductors and is thought to help maintain the neutral position of the hip. The third muscle, the semimembranosus, originates in the hip flexors and is thought to contribute to a degree of stability to hip joint movements. Finally, the tibial tuberosity originates in the front of the thigh and helps to determine the angle of travel in walking and running. The tibial tuberosity is referred to as the CCD angle, and its presence demonstrates an approximate correlation between the amount of available space for one's body weight in walking and running.
