Sensory Perception

STUDY
PLAY
Identify the stimulus detected by each class of sensory receptors.
• Mechanoreceptors - mechanical energy (touch, vibration, pressure) • Pain Receptors - Tissue damaged • Thermoreceptors -Temperature • Chemoreceptor - Chemical Energy • Osmoreceptor -Change in concentration of solute in bodily fluid • Photoreceptors - Light all will make brain think
State what all sensory neurons transducer stimulus energy into.
• Sensory receptors transduce energy of a specific stimulus, such as pressure, heat, or light into the electrochemical energy of action potential.
Describe somatic sensations (what are they, and how are they sensed)
• Touch and Warmth (skin muscle)
• Responses to receptors near the body surface and in skeletal muscles, joints, and walls of soft internal organs.
• Free nerve endings, or branched endings of sensory neurons, are the most abundant receivers of somatic information.
function of substance P
• Enhances pain perception
• When tissue damage happens it releases substance P, which are the pain receptors.
main taste sensations
There are 5 main sensations
1. Sweet - Sugar to make ATP
2. Sour - Acids
3. Salty - Sodium
4. Bitter - Plant Toxins
5. Umami - Amino Acids
Describe the functions and structures of the outer, middle, and inner ear.
Outer ear gathers sound, Middle ear amplifies and transmits air waves to inner ear, Inner ear transduces sound waves into action potential
Describe the function of the outer ear
outer ear gathers sound
Describe the function of the middle ear
Middle ear amplifies and transmits air waves to inner ear
Describe the function of the inner ear
inner ear transduces sound waves into action potential
What are the 5 main taste sensations
sweet, sour, salty, bitty, and unami
Explain the minimal requirements for a sense of vision
eyes and brain with the capacity to interpret visual stimulation
