The appendicular skeleton is composed of bones that form 1) the upper limbs (arms), 2) the lower limbs (legs), 3) the pectoral or shoulder girdle, and 4) the pelvic or hip girdle. The pectoral girdle helps attach the upper limbs to the body trunk while the pelvic girdle attaches the lower limbs to the body trunk.
The bones of the appendicular skeleton make up the rest of the skeleton, and are so called because they are appendages of the axial skeleton. The appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.
Likewise, what is the largest long bone of the appendicular skeleton? humerus
Thereof, what does the appendicular skeleton consist of?
The human appendicular skeleton is composed of the bones of the upper limbs, the lower limbs, the pectoral girdle, and the pelvic girdle. The pectoral girdle acts as the point of attachment of the upper limbs to the body. The upper limb consists of the arm, the forearm, and the wrist and hand.
Which of these bones is part of the axial skeleton?
The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate. In the human skeleton, it consists of 80 bones and is composed of six parts; the skull (22 bones), the ossicles of the middle ear, the hyoid bone, the rib cage, sternum and the vertebral column.
What is the importance of the appendicular skeleton?
The appendicular skeleton bones are vital for movement, locomotion, and overall function of the human body. They provide support and attachment locations for the major muscles groups that impart motion and stability of the physical structure of the body.
How many bones are in the body?
How many bones are in the pectoral girdle?
How many bones are in your skull?
The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteen facial skeleton bones. In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones.
What are the 206 bones?
The human skeleton is made up of 206 bones, including bones of the: Skull – including the jaw bone. Spine – cervical, thoracic and lumbar vertebrae, sacrum and tailbone (coccyx) Chest – ribs and breastbone (sternum) Arms – shoulder blade (scapula), collar bone (clavicle), humerus, radius and ulna.
What is the longest bone in the body?
What are the types of bones?
There are five types of bones in the skeleton: flat, long, short, irregular, and sesamoid. Let’s go through each type and see examples.
What are the classification of bones?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities.
What does appendicular mean in medical terms?
Medical Definition of appendicular : of or relating to an appendage: a : of or relating to a limb or limbs the appendicular skeleton. b : appendiceal.
What are the two types of skeleton?
Types of skeletons. There are two major types of skeletons: solid and fluid. Solid skeletons can be internal, called an endoskeleton, or external, called an exoskeleton, and may be further classified as pliant (elastic/movable) or rigid (hard/non-movable). Fluid skeletons are always internal.
What is the difference between appendicular and axial skeleton?
Overview. We are composed of one skeleton that can be divided into two major regions, the axial and appendicular skeleton. The axial skeleton makes up our central axis and consists of the following bones: skull, vertebrae, ribs and sternum. The appendicular skeleton consists of the limbs and girdles.
What is compact bone?
Compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells. Both types are found in most bones.
What is the function of the axial skeleton?
The axial skeleton supports and protects the brain, spinal cord and many of the internal organs. It also provides sites for the attachment of other bones and muscles in the body and protects the nerves and blood vessels from the brain and spinal cord.
