Written by renowned authors Gerard J. Tortora and Bryan H. Derrickson, this book takes an integrative approach, seamlessly connecting anatomy and physiology to provide a holistic understanding of the human body.
The textbook is organized into 10 units, each covering a major body system. Each unit begins with an overview of the system, followed by chapters that explore the specific structures and functions of its components. The authors use a clear and concise writing style, making complex concepts accessible to students.
This 4th edition has been updated with the latest research and advancements in the field of anatomy and physiology. It also includes new and revised illustrations, interactive exercises, and case studies to enhance student learning.
The Skeletal System
The skeletal system is a complex and dynamic system that provides support, protection, and movement for the body. It consists of bones, joints, and cartilage, and works in conjunction with the muscular system to enable movement.
Structure and Function of Bones
- Bones are hard, mineralized tissues that provide support and protection for the body.
- They are composed of a protein matrix called collagen, which provides flexibility, and a mineral matrix called hydroxyapatite, which provides strength.
- Bones are classified into different types based on their shape and function, including long bones, short bones, flat bones, and irregular bones.
Bone Formation and Remodeling
Bones are constantly being remodeled throughout life. This process involves the breakdown of old bone tissue by cells called osteoclasts and the formation of new bone tissue by cells called osteoblasts.
Role of the Skeletal System
- Support: The skeletal system provides support for the body and helps maintain its posture.
- Protection: Bones protect vital organs, such as the brain, heart, and lungs, from injury.
- Movement: The skeletal system works with the muscular system to enable movement.
- Mineral storage: Bones store minerals, such as calcium and phosphorus, which are essential for various bodily functions.
- Blood cell production: Bone marrow, located within the cavities of bones, produces red blood cells, white blood cells, and platelets.
The Muscular System
The muscular system is responsible for movement, posture, and heat production. It consists of muscles, which are specialized tissues that can contract and relax.
Structure and Function of Muscles, Anatomy and physiology an integrative approach 4th edition
- Muscles are composed of bundles of muscle fibers, which are long, cylindrical cells that contain contractile proteins.
- There are three types of muscles: skeletal muscles, smooth muscles, and cardiac muscles.
- Skeletal muscles are attached to bones and are responsible for voluntary movement.
- Smooth muscles are found in the walls of organs and blood vessels and are responsible for involuntary movements.
- Cardiac muscles are found only in the heart and are responsible for the rhythmic contractions that pump blood.
Muscle Contraction and Relaxation
Muscle contraction occurs when the contractile proteins within muscle fibers slide past each other. This process is initiated by nerve impulses and requires energy in the form of ATP.
Muscle relaxation occurs when the contractile proteins detach from each other, allowing the muscle to return to its resting length.
Role of the Muscular System
- Movement: The muscular system enables movement of the body, including locomotion, posture, and manipulation of objects.
- Posture: Muscles maintain posture by keeping the body upright and balanced.
- Heat production: Muscles generate heat as a byproduct of contraction, which helps maintain body temperature.
- Protection: Muscles protect vital organs by providing a physical barrier and by generating heat.
