Study Notes
Musculoskeletal Anatomy
- Bones form the skeletal framework, providing support and protection.
- Cartilage cushions joints and facilitates smooth movement.
- Ligaments connect bones to other bones, providing joint stability.
- Tendons connect muscles to bones, enabling movement.
- Muscles contract to produce movement, and they are responsible for posture and heat generation.
- Joints are the areas where two or more bones meet, allowing for various degrees of movement.
- Types of joints include: fibrous, cartilaginous, and synovial joints.
- Synovial joints are characterized by a synovial fluid-filled cavity that reduces friction during movement.
Cardiovascular Physiology
- The heart is a muscular pump that propels blood throughout the body.
- The heart's four chambers (two atria and two ventricles) work in a coordinated manner to ensure efficient blood flow.
- The heart has valves (tricuspid, mitral, pulmonary, and aortic) to maintain one-way blood flow.
- Blood vessels (arteries, veins, and capillaries) form a network that transports blood throughout the body.
- Arteries carry oxygenated blood away from the heart.
- Veins carry deoxygenated blood back to the heart.
- Capillaries allow for the exchange of gases and nutrients between blood and tissues.
- Blood is composed of plasma, red blood cells, white blood cells, and platelets.
- Blood pressure is the force exerted by blood against the walls of the blood vessels.
- Blood pressure regulation is crucial for maintaining adequate blood flow to organs and tissues.
Respiratory Anatomy
- The respiratory system facilitates gas exchange, taking in oxygen and releasing carbon dioxide.
- The nose and nasal passages warm and humidify incoming air, filtering out foreign particles.
- Pharynx (throat) is a common passageway for both air and food.
- Larynx (voice box), protects airway, houses vocal cords.
- Trachea (windpipe), is the main airway for air to pass to and from the lungs.
- Lungs contain millions of alveoli, tiny air sacs where gas exchange occurs.
- Diaphragm and intercostal muscles are responsible for breathing movements.
- Gas exchange occurs via diffusion across the thin alveolar walls.
- The respiratory system functions in conjunction with the cardiovascular system for oxygen transport.
Nervous System Function
- The nervous system controls and coordinates body functions.
- The central nervous system (CNS) consists of the brain and spinal cord.
- The peripheral nervous system (PNS) comprises nerves outside the CNS.
- Neurons are the fundamental units of the nervous system, transmitting signals throughout the body.
- Action potentials are electrical signals that travel along neurons.
- Neurotransmitters transmit signals between neurons and other cells.
- The nervous system has different regions specialized for different tasks.
- Sensory neurons transmit information from sensory receptors to the CNS.
- Motor neurons transmit signals from the CNS to muscles and glands.
- The nervous system plays a vital role in reflexes, and higher-level functions like thought, memory, and consciousness.
