The bones of the human being skeleton are divided into two groups. The axial skeleton contains all the bones (that kind bony structures) follow me the body’s long axis. The skeleton of the appendicular skeleton comprise the remainder of the skeleton, and also are for this reason called because they are appendages that the axial skeleton. The appendicular skeleton includes the bones of the shoulder girdle, the top limbs, the pelvic girdle, and the lower limbs.

Let’s take a look at the bones of the appendicular skeleton.

1. The skeleton of the Shoulder Girdle

*

The pectoral or shoulder girdle is composed of the scapulae and also clavicles. The shoulder girdle associate the bones of the upper limbs come the axial skeleton. These bones also administer attachment for muscles that relocate the shoulders and also upper limbs.

2. Bones of the top Limbs

*

The upper limbs encompass the skeleton of the arm (humerus), forearm (radius and ulna), wrist, and also hand. The just bone the the arm is the humerus, i m sorry articulates v the forearm bones–the radius and also ulna–at the elbow joint. The ulna is the larger of the 2 forearm bones.

*

Wrist Bones. The wrist, or carpus, is composed of eight carpal bones. One mnemomic to remember the carpal bones is the sentence: Some Lovers Try Positions That They Can’t Handle. The eight carpal skeleton of the wrist are the Scaphoid, Lunate, Triquetral, Pisiform, Trapezoid, Trapezium, Capitate, Hamate.

*
Hand Bones. The hand consists of 8 bones in the wrist, 5 skeletal that type the palm, and 14 bones that kind the fingers and thumb. The wrist skeletal are called carpals. The skeletal that form the palm of the hand are called metacarpals. The phalanges room the skeleton of the fingers.

3. The bones of the Pelvis

*

The pelvic girdle is a ring of bones attached come the vertebral tower that connects the bones of the reduced limbs to the axial skeleton. The pelvic girdle is composed of the right and also left i know well bones. Every hip bone is a large, flattened, and also irregularly shaped blend of three bones: the ilium, ischium, and pubis.

*
Female and Male Pelvis. The female and also male pelvises differ in several ways because of childbearing adaptations in the female.

The female pelvic brim is bigger and wider than the male’s.The angle of the pubic arch is better in the mrs pelvis (over 90 degrees) 보다 in the masculine pelvis (less 보다 90 degrees).The male pelvis is deeper and has a narrower pelvic outlet than the female’s.

4. The skeleton of the lower Limbs

*

The lower limbs encompass the skeletal of the thigh, leg, and also foot. The femur is the only bone that the thigh. The articulates with the 2 bones of the leg–the larger tibia (commonly known as the shin) and smaller fibula. The thigh and also leg bones articulate at the knee joint that is protected and magnified by the patella bone the supports the quadriceps tendon. The bones of the foot incorporate the tarsus, metatarsus, and also phalanges.

*

Foot Bones. The skeletal of the foot covers the tarsal bones of the ankle, the phalanges that kind the toes, and also the metatarsals that offer the foot the arch. Together in the hand, the foot has five metatarsals, 5 proximal phalanges, five distal phalanges, but only four middle phalanges (as the foot’s “big toe” has actually only two phalanges).

*

Ankle Bones. The ankle, or tarsus, consists of seven tarsal bones: the calcaneus, talus, cuboid, navicular, and also three cuneiforms.

*

Foot Arches. The arches of the foot are created by the interlocking bones and also ligaments that the foot. They serve as shock-asborbing frameworks that assistance body weight and distribute tension evenly during walking.

The longitudinal arch of the foot runs from the calcaneus to the top of the metatarsals, and also has medial and lateral parts.The transverse arch of the foot runs across the cuneiforms and also the base of the metatarsal bones.
