What are the parts of axial skeleton?
Axial skeleton. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull bones, the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column. The axial skeleton together with the appendicular skeleton form the complete skeleton. Another definition of axial skeleton is...
What is the difference between the axial and appendicular skeleton?
Your axial skeleton is made up of the bones in your head, neck, back and chest. Your appendicular skeleton is made up of everything else — the bones that attach (append) to your axial skeleton. Your appendicular skeleton includes the bones in your shoulders, pelvis and limbs, including your arms, hands, legs and feet.
Is pelvis axial or appendicular?
The appendicular skeleton is everything else. It's everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.

What are the bones of the axial skeleton?
We will make a list of bones of the axial skeletal system by segregating the axial skeleton in the following parts: 1 Skull: A human skull consists of 28 different bones, and is divided into two main parts called the cranium and facial bones. 2 Sternum/Breastbone: This is one flat bone that anchors the ribs, and together the sternum and ribs comprise the rib cage. 3 Ribs: It contains 24 bones forming 12 pairs of ribs, which are further divided into true and false ribs. 4 Vertebral Column: The vertebral column or spine, is made up of 33 irregularly shaped bones, which are divided into five categories: the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, the sacrum, and finally the coccyx or tail-bone.
What is the other part of the skeletal system called?
The other part of the human skeletal system is called the appendicular skeleton, and together with the axial skeleton, it completes the human skeletal system.

What is the function of the pelvis?
The femur is the appendicular skeletal bone connected to the pelvis at the acetabulum, a bony ring formed by the fusion of three bones: the ilium, ischium, and pubis. The main function of the pelvis is support for locomotion, as it provides attachment points for muscles , tendons , and ligaments. While stiff joints bind the axial skeleton to the pelvis, the appendicular skeleton is joined via a relatively free-floating ball and socket joint between the femur and the acetabulum to allow maximal mobility of the joint.[1]
What is the ligament of the head of the femur?
Other ligaments of note in the acetabulum are the transverse acetabular ligament and the ligament of the head of the femur, or ligamentum teres femoris (Latin for round ligament of the femur.) The transverse acetabular ligament is a strong band of connective fibers that traverse the acetabular notch on the inferior aspect of the acetabulum, this creates a foramen for nutrient-supplying blood vessels to enter the hip joint while still maintaining the structural integrity of the joint. Much as its name implies, the ligament of the head of the femur is connected to the head of the femur at the center of the acetabulum. However, rather than providing support, its main function is to house the artery to the head of the femur, which provides blood to the head of the femur via a branch from the obturator artery. Disruption in perfusion to the femoral head from any cause can result in degradation and even collapse of the femur inside the acetabulum. This disease process is known as avascular necrosis or Legg-Calve-Perthes disease in children.
How many variants of the pelvis are there?
The most significant physiologic variants of the pelvis are relevant to child-bearing. There are 4 recognized variants of the pelvis as classified by the "Caldwell-Moloy" system. [8]
Which joint is a relatively free floating ball and socket joint?
While stiff joints bind the axial skeleton to the pelvis, the appendicular skeleton is joined via a relatively free-floating ball and socket joint between the femur and the acetabulum to allow maximal mobility of the joint.[1] The pelvis is a group of fused bones and may be considered the first step in the linkage of the axial skeleton ...
Where is the iliac crest located?
The iliac crest is the most superior part of the pelvis located near what is commonly referred to as the waist. This level corresponds to around L3-L4 lumbar vertebrae and can be used to safely place a lumbar puncture needle by minimizing the potential for spinal cord damage while still accessing cerebrospinal fluid, as the cord itself ends around the L1 vertebral level.

What are the bones of the pelvis?
Bones of the Pelvis. There are three bones of the pelvis: the hip bone, sacrum and coccyx. These bones connect the axial skeleton to the lower limbs, and therefore play a role in bearing the weight of the upper body. These bones also act as attachments for many muscles and ligaments within the pelvis and lower limbs.
Which bones are the smallest in the pelvic system?
It is formed by the fusion of five sacral vertebrae, and transmits the sacral nerve fibres of the cauda equina. The coccyx, commonly referred to as the tailbone , is the smallest of the pelvic bones, and sits inferiorly to the sacrum.
Where is the pelvic girdle located?
The pelvic girdle is the ring shaped collection of these bones at the base of the spine.
What are the parts of the hip?
The hip bone has three parts: the ilium, pubis and ischium. These are separated by cartilage at birth and fuse during puberty. The sacrum is located inferiorly to the spinal vertebrae, and posteriorly within the pelvis. It is formed by the fusion of five sacral vertebrae, and transmits the sacral nerve fibres of the cauda equina.

What are the bones that make up the skull?
The human skull consists of the cranium and the facial bones . The cranium holds and protects the brain in a large space called the cranial vault. The cranium is formed from eight plate-shaped bones which fit together at meeting points (joints) called sutures. In addition there are 14 facial bones which form the lower front part of the skull. Together the 22 bones that compose the skull form additional, smaller spaces besides the cranial vault, such as the cavities for the eyes, the internal ear, the nose, and the mouth. The most important facial bones include the jaw or mandible, the upper jaw or maxilla, the zygomatic or cheek bone, and the nasal bone.
Where are the rounded ends of the ribs?
The rounded ends are attached at joints to the thoracic vertebrae at the back and the flattened ends come together at the sternum, in the front. The upper seven pairs of ribs attach to the sternum with costal cartilage and are known as “true ribs.”.
