Document Summary
Chapter 1 an introduction to the human body. Standardized terminology when talking to other health professions to determine locations. Sagittal right and left, doesn"t have to be along the mid line (midsagittal) Cranial cavity brain, spinal column, runs all the way down spinal column to torso, includes vertebral cavity. All cavities have membrane that lines outer and inner portion, called serous membrane. Parietal layer covers outer part of rib cage. Secrets fluid to reduce friction caused by rubbing. Related to muscles, anterior, posterior and anterior compartments. Cells made up of atoms and molecules. Important life processes: metabolism, responsiveness, movement, growth, differentiation, reproduction. Chemical level (atoms) cellular level (molecule dna) tissue level (smooth muscle tissue) organ level (stomach) system level (digestive) organismal level. Golgi complex modifies, sorts, packages, and transports protein. Proteasome breaks down foreign invaders or damaged material, releases enzymes to break them down. Mitochondria generates energy (oxygen to atp), oxidative phosphorylation. Lysosomes digest substances that enter cell.
