The bones of the pelvic girdle and lower limb play a crucial role in the movement and support of the human body. The pelvic girdle is a bony structure that connects the lower limbs to the axial skeleton, providing a strong and stable base for the body. It consists of two hip bones, which are joined together at the pubic symphysis and form the pelvis.

The hip bones, also known as the coxal bones or innominate bones, are irregularly shaped bones that are located on either side of the pelvis. They consist of three parts: the ilium, ischium, and pubis. The ilium is the largest and most superior part of the hip bone, and it forms the superior margin of the pelvis. The ischium is the inferior and posterior part of the hip bone, and it forms the posterior margin of the pelvis. The pubis is the anterior part of the hip bone, and it forms the anterior margin of the pelvis.

The pelvic girdle also includes the sacrum and coccyx, which are fused bones that form the posterior part of the pelvis. The sacrum is a triangular-shaped bone that is located between the hip bones and is attached to the lumbar vertebrae. The coccyx, also known as the tailbone, is a small, triangular bone that is located at the inferior end of the sacrum.

The lower limb consists of the thigh, leg, and foot. The thigh is the upper part of the leg and is composed of the femur, which is the longest and strongest bone in the body. The femur connects the pelvis to the knee joint and is responsible for bearing the weight of the body. The leg is the lower part of the leg and is composed of the tibia and fibula, which are long bones that form the shin. The tibia, also known as the shinbone, is the larger and more medial bone of the leg, and it is the main weight-bearing bone of the lower leg. The fibula is the smaller and more lateral bone of the leg, and it is not involved in weight bearing.

The foot is the inferior part of the lower limb and consists of the tarsal bones, metatarsal bones, and phalanges. The tarsal bones form the posterior part of the foot and include the calcaneus, talus, and navicular bones. The calcaneus, also known as the heel bone, is the largest and strongest bone of the tarsal bones, and it forms the posterior part of the foot. The talus is a small bone that is located between the tibia and fibula and the calcaneus, and it forms the ankle joint. The navicular bone is a boat-shaped bone that is located on the medial side of the foot, and it helps to support the arch of the foot.

The metatarsal bones form the middle part of the foot and include the first, second, third, fourth, and fifth metatarsal bones. These bones connect the tarsal bones to the phalanges, which are the bones of the toes. The phalanges include the proximal phalanges, which are located near the metatarsal bones, and the distal phalanges, which are located at the tips of the toes.

In conclusion, the bones of the pelvic girdle and lower limb play a crucial role in the movement and support of the human body. The pelvic girdle provides a strong and stable base for the body, while the lower limb allows for the movement of the body and supports the weight of the body. These bones work

An easy way to find your pelvic floor is to just sit down. The femoral neck is separated from the shaft anteriorly by the intertrochanteric line and posteriorly by intertronchanteric crest. Take this quiz and reinforce your knowledge about the lower limb anatomy! Coxal bones together with the coccyx and the sacrum constitute the pelvis. Anteriorly:Its head form joint with the navicular called as talonavicular joint. Pelvic girdle— Comprises the sacrum and the hip bone. Tibia Tibia is the large weight bearing medial bone of the leg.

This is located at the inferior end of a large, roughened area called the auricular surface of the ilium. Fibula The weak lateral bone of the leg which doesn't take part in the weight bearing. What is the female pelvis? The large, inverted U-shaped indentation located on the posterior margin of the lower ilium is called the greater sciatic notch. Comparison of the Female and Male Pelvis The differences between the adult female and male pelvis relate to function and body size. With the onset of puberty, the male pelvis remains on the same developmental trajectory, while the female pelvis develops in an entirely new direction, becoming wider and reaching its full width around the age of 25-30 years. A deformity of the socket pincer impingement. The male pelvis is more robust, narrower, and taller than the female pelvis.

They are proximal, middle, and distal. How do I lose my FUPA? The pubic bones form a cartilaginous joint in the median plane, the symphysis pubis. The body of the pubis articulates with the pubis of the opposite hip bone at the pubic symphysis. Keep in mind, however, that the term describes the shape of a bone, not its size. Anteriorly: Calcaneum forms the joint with the cuboid bone.

The pubis forms the anterior portion of the hip bone. No real point here, other than reaching for a way to remember the terminology! The narrow ridge running along the superior margin of the superior pubic ramus is the pectineal line of the pubis. At the time of puberty, these sections fuse forming one bone. How do I find my pubic symphysis? Tendons are a dense connective tissue that connect bones to muscles and sesamoid bones form where a great deal of pressure is generated in a joint. Chapter Review The pelvic girdle, consisting of two hip bones, serves to attach the lower limbs to the sacrum of the axial skeleton. Inferiorly: On the medial side of the calcaneum is the shelf likeprocess called sustenaculum talus.

In contrast, the pectoral girdle is very mobile. This important bony landmark can be felt at your anterolateral hip. As a result of the depth of the acetabulum and its shape, the complete head of the femur can be confined by it. While pelvis shape can vary widely among females, there are four general types: gynecoid, android, anthropoid, and platypelloid.

The shaft of the femur convex anteriorly presents anterior, medial, and lateral surfaces. The joint connects the lower extremities with that of the axial skeleton. Additionally, the female pelvis has a subpubic angle greater than 90° angle formed below and between the two pubic bones. It collects blood transported by all the veins of the leg and empties into the femoral vein. Note that during walking the talus transmits some body weight to the metatarsals through the calcaneus and cuboid bones and the ground when the calcaneus is in contact with it. Malformations impair these functions and distort the appearance of the upper chest and back. The sacrospinous ligament runs from the sacrum to the ischial spine, and the sacrotuberous ligament runs from the sacrum to the ischial tuberosity.

The main vein draining the thigh, and actually the entire lower limb, is the femoral vein. In comparison to the upper limb, the muscles and bones of the lower limb are much stronger and larger. The pelvic brim is defined by a line formed by the upper margin of the pubic symphysis anteriorly, and the pectineal line of the pubis, the arcuate line of the ilium, and the sacral promontory the anterior margin of the superior sacrum posteriorly.
