Between the ischium and the pubis is an almost round hole. This is called obturator foramen. It is covered by a membrane called obturator.

The pubis lies anteriorly below the ilium. It consists of 3 parts. Upper arm, lower arm and body. The superior arm or rami consists of a pubic crest or crest and a pubic tuberosity. The two pubis on either side meet at the mid-digital line to form the pubic symphysis. Pubic arch is less than 900 in men and more than 900 in women.

Ischium is below the ilium. It consists of a main body, two arms or rami, lobes and spines. It has spines on top and tubercles or tubercles on the bottom.

Ilium is a large and flat bone. It consists of body and wings. Its high point is called the ilium crest or ridge. Above it are anterior superior and posterior superior and below anterior inferior and posterior inferior. In addition, the ilium contains 3 gluteal lines, an arcuate line, an iliac fossa and an auricular floor.

Pelvis consists of two equal parts. Each part is called a hip bone or innominate bone or oscoxia or hip bone. Each hip bone consists of three parts.

Pelvis consists of two equal parts. Each part is called a hip bone or innominate bone or oscoxia or hip bone. Each hip bone consists of three parts. These are-
1. Ilium: Ilium is a large and flat bone. It consists of body and wings. Its high point is called the ilium crest or ridge. Above it are anterior superior and posterior superior and below anterior inferior and posterior inferior. In addition, the ilium contains 3 gluteal lines, an arcuate line, an iliac fossa and an auricular floor.
2. Ischium: Ischium is below the ilium. It consists of a main body, two arms or rami, lobes and spines. It has spines on top and tubercles or tubercles on the bottom.
3. Pubis: The pubis lies anteriorly below the ilium. It consists of 3 parts. Upper arm, lower arm and body. The superior arm or rami consists of a pubic crest or crest and a pubic tuberosity. The two pubis on either side meet at the mid-digital line to form the pubic symphysis. Pubic arch is less than 900 in men and more than 900 in women.
4. Obturator foramen: Between the ischium and the pubis is an almost round hole. This is called obturator foramen. It is covered by a membrane called obturator.
5. Acetabulum: At the junction of ilium, ischium and pubis is a shallow hole called acetabulum. The acetabulum holds the head of the femur.

Finger bones are called phalanges. The phalanges are 14 in number. There are 2 bones in the thumb and 3 in the other fingers. Distal, Middle and Proximal. They are short and cylindrical bones.

Metacarpal unstable digit 5. Thumb, Index finger, Middle finger, Ring finger and Little finger. Each metacarpal bone consists of three parts. Head, body and base.

There are 8 carpal bones, 4 each in two rows of the wrist. The upper row consists of 4 bones Scaphoid or Nevicular, Lunate, Triquetal and Pisiform. The lower row consists of 4 bones Trapezium, Trapezoid, Capitate and Hamate.

The two bones below the humerus are called Radius-Ulna. Of these, the outer bone is called the radius and the inner bone is called the ulna. The radius and ulna are connected by a membrane called the interosseous membrane. The upper part of both bones is covered by the annular membrane and the lower part by the antibrachial sheath. The radius consists of the head, neck and lobes at the top and the styloid process at the bottom. Again, the upper part of the ulna consists of the coronoid process, olecranon process, trochlear notch and tuberosity and the lower part the styloid process.
