HUMAN PHYSIOLOGY
HUMAN PHYSIOLOGY Human physiology is the study of the functions and processes of the human body, focusing on how various systems interact to maintain homeostasis and support life. 1. Nervous System Function: Controls and coordinates body activities by transmitting signals between different parts of the body. Components: Includes the brain, spinal cord, and peripheral nerves. Key Concepts: Neurons, synapses, neurotransmitters, reflex arcs. 2. Endocrine System Function: Regulates bodily functions through hormones released into the bloodstream. Components: Glands such as the pituitary, thyroid, adrenal, and pancreas. Key Concepts: Hormonal regulation of metabolism, growth, reproduction, and stress response. 3. Muscular System Function: Facilitates movement and maintains posture. Types of Muscle: Skeletal (voluntary), cardiac (involuntary), and smooth (involuntary). Key Concepts: Muscle contraction mechanisms, energy metabolism in muscles. 4. Skeletal System Function: Provi...
