Document Summary
Lateral line: detect movements far away from them, they don t have to touch directly with ns or body. Can feel the current (i. e feel wind around us) Can feel things around it (i. e. feeling seagull beat wings above our heads) Biotic: yourself, (i. e. running, you move through air), prey, predators, conspeci cs (others moving around you) Sensory hair cell: involved in sensory line receptor. Recall cilia= thin extension of cell(hair-like), built in structure with microtubules that can move. Tree: sensory hair cells are extremely old, atleast as old as the chordates (showed up before jawed vertebrates) Lost after amphibians (thus we don t have it) : two internal related systems, 1= electrosensory systems, 2= lateral linethey develop in similar areas of the sh. Neuromast- sensory hair cells together, stereocilia and kinocilia extend into a. Glucose amino-glycan, similar to jelly- sh coating , or jello-like covering (which is quite.
