"A skeleton is the structural frame that supports the body of most animals."
The system of bones and cartilage that gives the body structure and protects organs.
Anatomy: The study of the structure of the human body, including the bones, joints, and related structures.
Physiology: The study of the functioning of the skeletal system, including how it supports the body, moves it, and protects it.
Biomechanics: The study of the mechanical properties of the skeletal system, including its ability to withstand stress and strain, and the relationship between structure and function.
Osteology: The study of bones, including their anatomy, structure, and development.
Histology: The study of the microstructure of bone tissue, including its composition, organization, and function.
Pathology: The study of skeletal system diseases, including their causes, symptoms, and treatment.
Developmental biology: The study of how the skeletal system develops over time, including embryonic and postnatal development.
Evolutionary biology: The study of the evolution of the skeletal system across different species and over time.
Clinical biomechanics: The application of biomechanical principles to the diagnosis and treatment of skeletal system disorders.
Sports biomechanics: The application of biomechanical principles to the study of athletic performance and injury prevention in sports.
Rehabilitation biomechanics: The application of biomechanical principles to the design of rehabilitation interventions for individuals with skeletal system disorders.
Radiography: The use of imaging techniques to visualize the skeletal system, including X-rays, CT scans, and MRI scans.
Anatomy and physiology of bones: Understanding the different types of bones and their functions, the composition of bone tissue, and the process of bone growth and remodeling.
Anatomy and physiology of joints: Understanding the different types of joints, their structure, function, and range of motion.
Muscles and their attachment to bones: Understanding the role of muscles in the movement of the skeletal system and how they are attached to bones.
Skeletal diseases and disorders: Understanding common skeletal system disorders such as osteoporosis, osteoarthritis, and rheumatoid arthritis, along with their causes and treatments.
Artificial joints: Understanding the design and function of artificial joints, their benefits and limitations, and how they are implanted.
Injury prevention: Understanding the ways in which injuries to the skeletal system can be prevented through proper training, conditioning, and protective equipment.
Nutrition: Understanding the role of nutrition in bone health and the prevention of skeletal system disorders.
Aging and the skeletal system: Understanding the impact of aging on the skeletal system, including changes in bone density and strength, and the increase in risk of skeletal system disorders.
"There are several types of skeletons..."
"...the exoskeleton, which is a rigid outer shell that holds up an organism's shape..."
"...the endoskeleton, a rigid internal frame to which the organs and soft tissues attach..."
"...the hydroskeleton, a flexible internal structure supported by the hydrostatic pressure of body fluids."
"Vertebrates are animals with an endoskeleton centered around an axial vertebral column..."
"...their skeletons are typically composed of bones and cartilages."
"Invertebrates are other animals that lack a vertebral column..."
"...their skeletons vary, including hard-shelled exoskeleton (arthropods and most molluscs), plated internal shells (e.g. cuttlebones in some cephalopods) or rods (e.g. ossicles in echinoderms), hydrostatically supported body cavities, and spicules."
"Cartilage is a rigid connective tissue that is found in the skeletal systems of vertebrates and invertebrates."
