Study Notes
Human Anatomy
- Human anatomy is the branch of biology that studies the structure of the human body.
- It encompasses the study of cells, tissues, organs, and organ systems.
- Anatomical structures are studied in a systematic way, often by region or system.
Levels of Organization
- The human body is organized in a hierarchical manner.
- The smallest unit is the cell, which is the basic structural and functional unit of life.
- Tissues are groups of similar cells working together.
- Organs are structures composed of different tissue types performing specific functions.
- Organ systems are groups of organs working together to perform a major body function.
Body Cavities
- Body cavities are spaces within the body that house and protect internal organs.
- The major cavities include the dorsal cavity (cranial cavity and vertebral canal) and the ventral cavity (thoracic cavity and abdominopelvic cavity).
Skeletal System
- The skeletal system provides support and protection for the body.
- Bones form a framework for muscles to attach to and move.
- Key functions include support, protection, movement, mineral storage, and blood cell production.
- Bones are classified by shape (long, short, flat, irregular).
- Bones consist of compact and spongy bone tissue, cartilage, and bone marrow.
Muscular System
- The muscular system allows for movement.
- Muscles contract to produce force and movement.
- Three types of muscle tissue exist: skeletal, smooth, and cardiac muscle.
- Skeletal muscle is responsible for voluntary movement.
- Smooth muscle is responsible for involuntary movement in the internal organs.
- Cardiac muscle is responsible for the contraction of the heart.
Nervous System
- The nervous system is responsible for communication and control within the body.
- The system consists of the brain, spinal cord, and nerves.
- The central nervous system (CNS) is composed of the brain and spinal cord.
- The peripheral nervous system (PNS) is composed of the nerves and ganglia outside the CNS.
- The nervous system controls various functions, including sensory perception, movement, thought, and emotion.
Endocrine System
- The endocrine system is responsible for regulating the body's functions through hormones.
- The system consists of glands that secrete hormones into the bloodstream.
- Hormones regulate many processes, such as growth, metabolism, and reproduction.
- Major glands include the pituitary, thyroid, adrenal, and gonads.
Cardiovascular System
- The cardiovascular system is responsible for transporting materials throughout the body.
- The system consists of the heart, blood vessels (arteries, veins, capillaries), and blood.
- The heart pumps blood throughout the body.
- Blood carries oxygen, nutrients, and waste products.
- Blood vessels transport blood.
Respiratory System
- The respiratory system is responsible for gas exchange (oxygen and carbon dioxide).
- The system consists of the lungs and associated structures (trachea, bronchi, alveoli).
- Breathing involves inhaling and exhaling air.
- Oxygen is absorbed from the air into the blood, and carbon dioxide is removed from the blood.
Digestive System
- The digestive system is responsible for breaking down food and absorbing nutrients.
- The system consists of the alimentary canal (mouth, esophagus, stomach, intestines) and accessory organs.
- Digestion involves mechanical and chemical breakdown of food.
- Nutrients are absorbed into the bloodstream and transported throughout the body.
Urinary System
- The urinary system is responsible for removing waste products from the blood and maintaining fluid balance.
- The system consists of the kidneys, ureters, bladder, and urethra.
- Kidneys filter waste products from the blood and produce urine.
- Urine is stored in the bladder and expelled from the body.
Lymphatic and Immune System
- The lymphatic system is part of the immune system and plays a role in fluid balance and immunity.
- Lymphatic vessels collect fluid that leaks out of capillaries, and return it to the bloodstream.
- Immune cells (lymphocytes) fight infection and disease.
- Lymph nodes are located along lymphatic vessels and filter lymph, which contains bacteria and other pathogens.
Integumentary System
- The integumentary system forms the external covering of the body.
- The skin, hair, and nails are parts of the system.
- The skin protects internal tissues and organs, regulates body temperature, and prevents water loss.
- The skin contains sensory receptors that detect touch, temperature, and pain.
Reproductive System
- The reproductive system is responsible for the production of offspring.
- The system differs in males and females.
- In males, the testes produce sperm, and the penis delivers sperm to the female reproductive tract.
- In females, the ovaries produce eggs, and the uterus is the site of gestation.
Regional Anatomy
- Regional anatomy studies the structures within a specific region of the body.
- It gives a more complex and detailed view of the organization and arrangement of structures in the specific region.
