starvation. • Senile atrophy in old age. Localized Atrophy: 1. Disuse atrophy: due to diminshed function‚ e.g. Atrophy of limb muscle after prolonged immobilization [bone fracture]. Atrophy of renal tubules after fibrosis of the corresponding glomerulus. 2. Pressure atrophy: due to continued pressure on tissues with decrease of its blood supply‚ e.g. Atrophy of vertebral bodies opposite aortic aneurysm [intervertebral discs don’t atrophy to same extent = avascular]. Atrophy of liver cells after

SENSE- is the ability to perceive stimuli. SENSATION (PERCEPTION)- is the conscious awareness of stimuli received by sensory receptors. GENERAL SENSES- are those with receptors distributed over a large part of the body. SOMATIC SENSES- provides sensory information about the body and the environment. VISCERAL SENSES- are more specialized in structure and are localized to specific parts of the body such as pain and pressure. SPECIAL SENSES- are more specialized in structure such as smell

Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus
