The Senses Jeopardy Template

Sense Organs	Taste	Smell	Hearing and Equilibrium
100 What is the amount of neurons present within a two point region that affects the amount of stimuli sent to the brain? Receptive Field	100 What is Lingual Papillae? The bumps on the tongue	100 What is the container of receptor cells for olfaction? Olfactory mucosa	100 What is high and low pitch? Frequency
200 What is the properties of receptors? 1. Sensory Transduction 2. Receptor Potential 3. Adaption	200 What are the three types of lingual papillae? 1. Filiform 2. Foliate 3. Vallate	200 What is different about nerve endings in smell? They are free and dangling	200 What is the part of the ear protected by the temporal bone? Inner Ear
300 What is the difference between fast pain and slow pain? Fast pain- travels on myelinated fibers Slow pain- travels on unmyelinated fibers	300 What is the importance of basal cells? They are stem cells that replace our taste cells.	300 What is the lifespan of olfactory cells? 60 days	300 What is the difference between proximal and distal ends of the cochlea? Proximal: Hairs for high frequency sounds Distal: Hairs for low pitched sounds
400 What is referred pain and give an example. Pain for a certain organ felt in a different part of the body. Ex. Heart attacks felt in arms or shoulders	400 What is the biological activity behind each of the five taste sensations? 1. Sweet: need to elevate blood sugar 2. Salty: need electrolytes 3. Sour and bitter: keep us from eating spoiled food 4.Umami: need amino acids	400 What is the difference between hydrophobic and hydrophilic in smell? Hydrophobic: Transport by odorant-binding protein Hydrophilic: Diffuse through mucus	400 What is vertigo? An inner ear disease that causes dizziness as a result of the buildup of otoliths.
500 What is the simple process of spinal gating that the man used in the video? 1. Descending analgesic fibers from reticular formation travel down spinal tract to dorsal horn 2. Secrete inhibitory substances to block substance P 3. Pain signals never ascend	500 What is the transduction pathway for taste? 1. Food chemicals bind to the chemoreceptors (taste cells) within the pores of the hairs. 2. AP's cause a nerve signal to be sent to the brain.	500 What is the transduction pathway for smell? 1. Molecules bind to receptors on olfactory hairs 2. Activate G protein and cAMP system. Opening ion channels for Na and Ca creating a receptor potential 3. Action potentials travel to the brain	500 What is the conduction pathway for the ear? 1. Vibrations cause a wave in the basilar membrane 2. The basilar membrane hits the tectorial membrane causing the hairs to bend 3. Receptors on the hairs send a signal to the brain detecting the type of sound produced.
