Document Summary
Basic organs & functions of organ systems basic life functions metabolism anabolism: simple > complex catabolism: complex > simple responsiveness organization growth and development reproduction regulation. Positive feedback loop: reinforces stimulus planes of the body sagittal: r-l frontal: anterior-posterior transverse: superior-inferior oblique: angled cavities quadrants general organs. 3 p + adenosine + ribose plasma membrane selectively permeable lipids + proteins phospholipids amphipathic polar heads non polar tails epithelial tissue continuous sheets closely packed together avascular: no blood supply high rate of cell division extensive innervation. Integumentary epidermis stratified squamous epithelial keratinocytes = 90% of epidermal cells melanocytes: store melanin. Bone fracture repair hematoma forms fibrocartilage callus forms hard callus forms bone is remodeled i. k. l. m. 3-4 fused sternum 3 fused bones: manubrium, body, diploid process. Muscle tissue t-tubules: excite entire muscle fiber simulateously sarcoplasmic reticulum: fluid-filled sacs that encircle each myofibril motor unit: somatic motor neuron + surrounding fibers. Ca released from sarcoplasmic reticulum into sarcoplasm .
