BSCI 201 Lecture Notes - Sliding Filament Theory, Extracellular Fluid, Neuromuscular Junction
Document Summary
The nervous system: neurons, neurotransmitters, ad action potentials, and neuromuscular junction. Muscles: both the physiology and anatomy, sliding filament theory. Study the structure and shape of the body and its parts. Study of how the body and its parts work or functions both on a microscopic and macroscopic level. Tissues collections of cells of the same type. Organs collection of two or more types of tissues put together into structures that perform a specific function. Organ systems collection of organs that work together to accomplish a task. Over 200 types of cells divided into 4 general categories. Epithelial barrier between body and external environment; change. For 70 kg man, total body water = 42 liters. Fluid that surrounds all of the body (liquid in blisters) All the extracellular fluid in the body except for plasma. Transport materials in the body via blood pumped by heart. Homeostasis is a central organizing principle of physiology.
