Basic Concepts in Anatomy and Physiology

Anatomyis the study of the structure of the body, while physiologyis the study of its function. Together, these disciplines provide a comprehensive understanding of the human body and how it works.

The human body is organized into different levels of structural organization:

• Chemical level:Atoms, molecules, and ions.
• Cellular level:Cells, the basic unit of life.
• Tissue level:Groups of similar cells that perform a specific function.
• Organ level:Structures composed of different tissues that perform a specific function.
• Organ system level:Groups of organs that work together to perform a specific function.
• Organismal level:The entire living organism.

Homeostasisis a fundamental concept in physiology. It refers to the body’s ability to maintain a stable internal environment despite changes in the external environment. Homeostasis is essential for optimal body function and survival.

The Skeletal System

The skeletal system provides support, protection, and movement for the body. It consists of bones, joints, and cartilage.

Types of Bones

• Long bones:Found in the limbs and provide support and movement.
• Short bones:Found in the wrists and ankles and provide stability.
• Flat bones:Found in the skull and pelvis and provide protection.
• Irregular bones:Found in the spine and provide support and protection.

Bone Formation and Growth

Bones are formed through a process called ossification. During this process, specialized cells called osteoblasts deposit calcium and other minerals to create bone tissue.

Bones grow in length and thickness through a process called appositional growth. In this process, new bone tissue is added to the surface of existing bone.

The Muscular System

The muscular system allows for movement and supports the body. It consists of muscles, tendons, and ligaments.

Types of Muscles, Biol 2401 anatomy and physiology i

• Skeletal muscles:Attached to bones and provide voluntary movement.
• Smooth muscles:Found in the walls of organs and provide involuntary movement.
• Cardiac muscles:Found in the heart and provide the rhythmic contractions necessary for pumping blood.

Muscle Contraction and Relaxation

Muscle contraction occurs when specialized proteins called actin and myosin slide past each other. This process requires energy in the form of ATP.

Muscle relaxation occurs when the actin and myosin filaments are separated, allowing the muscle to return to its resting state.
