The two major divisions of the skeletal system are?
Axial Skeleton: includes the head, neck, and trunk Appendicular Skeleton: upper and lower limbs
What are two parts of the skeletal system?
The two parts of the skeletal system are the appendicular skeleton and the axial skeleton. The axial skeleton contains the head, neck and trunk bones.The appendicular skeleton upper limbs with the pectoral girdle and the lower limbs with the pelvic girdle.
How are the extremities attached to the axial portion of the body?
The extremities, such as the arms and legs, are attached to the axial portion of the body through joints. The arms are attached to the axial skeleton through the shoulders, while the legs are attached through the hips. These joints allow for movement and flexibility.
What are the two division of skeletal system?
The axial and appendicular are the two divisions in the skeletal system. The axial skeleton consists of bones that form the axis of the body and support and protect the organs of the head, neck, and trunk the skull, the sternum, the ribs, the vertebral column The appendicular skeleton is composed of bones that anchor the appendages to the axial skeleton. The upper and lower extremities, the shoulder girdle, the pelvic girdle
What are two main divisions of human skeleton?
Axial Skeleton: forms the axis of the body(Examples: skull, vertebrae, rib cage)Appendicular Skeleton: limb bones and their girdles(Examples: Upper limbs, clavicle, scapula; lower limbs, pelvis)
Is the pectoral girdle a part of the axial division of the skeletal system?
If a straight line was made from the top of the skull straight down the spine to the ground, as in an axial division, the left side of the body including the pelvis would be a mirror image of the right side, so the body can be called bi-laterally symmetrical.
Important to relate the structures of the axial and appendicular skeleton to one another?
The Skeleton can be divided into Axial and Appendicular portions. The Axial Skeleton, is the head and trunk, and include the bones of the skull, hyoid bone, vertebral column, and thoracic cage. The Appendicular Skeleton, contains the pelvic and pectoral girdles, as well as the upper and lower limbs. The limbs and girdles, of the Appendicular Skeleton, attach to the Axial Skeleton.
Both the scapula and clavicle form joints with the axial skeleton is true or flase?
True. The scapula forms a joint with the axial skeleton at the sternum, while the clavicle forms a joint with the axial skeleton at the scapula. These joints allow for movement of the upper limbs and help support the upper body.
Which component of the skeletal system is made up of the upper and lower limbs and the pelvic and shoulder girdles?
The appendicular skeleton is the component of the skeletal system that consists of the upper and lower limbs, as well as the pelvic and shoulder girdles. This part of the skeleton is involved in movement and provides stability and support to the body.
How do name of two division of the skeletal system appendicular and axial provide cluse to the locations on a skeleton of the components in each division?
The term "appendicular" refers to the limbs or appendages, so the components in the appendicular division are found in the upper and lower limbs of the skeleton. "Axial" pertains to the axis of the body, so the components in the axial division are located along the central axis of the body, including the skull, vertebral column, and rib cage.
Why are the bones of the lower limbs larger and heavier than upper limbs?
The bones of the lower limbs are larger and heavier than the bones of the upper limbs because they must support the body's weight and provide stability during activities like walking, running, and jumping. The lower limbs also have larger muscle groups attached to them, which contribute to their increased size and strength compared to the upper limbs.
What is the scientific name for shoulder girdle?
The scientific name for the shoulder girdle is "pectoral girdle." It is the set of bones that connect the upper limbs to the axial skeleton.
