Study Notes
The human skeleton is a framework that serves as a support system for the body, made up of bones, cartilages, tendons, and ligaments It consists of two principal subdivisions: the axial and the appendicular skeleton The axial skeleton includes the vertebral column, skull, and rib cage, and the appendicular skeleton comprises the limb bones and the bones of the hands and feet
The hand and foot bones are part of the appendicular skeleton. The hand contains 28 bones, including the phalans, which are the bones of the fingers, and the bones of the hand The foot has 26 bones, including the phalans of the toes and the bones of the foot
The rib cage is part of the axial skeleton and is made up of 24 ribs, which form a cage that shelters the heart and lungs The rib cage also helps protect the bladder, part of the intestines, and in women, the reproductive organs
The skull structure is part of the axial skeleton and is made up of 22 bones, including the bones of the face, the skull, and the jaw The skull protects the brain and forms the shape of the face
The vertebral column, also part of the axial skeleton, is made up of 26 bones, including the 24 vertebrae, the sacrum, and the coccyx (tailbone) The vertebral column protects the spinal cord and provides stiffening for the body
The limb bones, such as the humerus in the upper arm and the femur in the thigh, are part of the appendicular skeleton These bones support the body and provide a point of attachment for muscles and ligaments
The human skeleton is a network of bones, cartilages, tendons, and ligaments that supports the body, protects its internal organs, and allows for movement The functions of the skeleton are support, protection, and motion, with support and protection evolve first and the axial part of the skeleton evolve first The skeleton is always remodeling, which allows the body to fix damaged bone, reshape the skeleton during growth, and regulate calcium levels The skeleton accounts for around 15% of the body's weight and contains 99% of the body's calcium The largest bone in the human body is the thighbone, or femur, and the smallest is the stapes in the middle ear, at around 0.002 0.003 0.004 0.005 0.006 0.008 0.010 0.012 0.014 0.016 0.018 0.020 0.022 0.024 0.026 0.028 0.030 0.032 0.034 0.036 0.038 0.040 0.042 0.044 0.046 0.048 0.050 0.052 0.054 0.056 0.058 0.060 0.062 0.064 0.066 0.068 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.069 0.
