BMEG 410 Lecture Notes - Lecture 1: Feedback, Golgi Apparatus, Thyroid
Document Summary
Negative feedback loop: shuts off system responsible for response. Feedforward mechanism: help prepare for an imminent change. Digestive: lysosomes, peroxisome, vacuoles (store fat, water, energy) Removal of vocal cords, patient loses voice and cannot communicate with others anymore. Treatment options: esophageal speech; burping to create vibration. Trachea-esophageal puncture: uses air from lungs; requires surgical maintenance. Electrolarynx: external vibration -> best case to fix to a more affordable version. An affordable and maintainable method to assist speech generation for laryngectomy patients in low- resource areas . Next steps: larger scale patient testing, presenting to clinical experts. Problem: quadriplegic athletes are not able to maintain a group on a racket for the duration of a match. Cervical level spinal cord injuries affect hand function. Hand dexterity, tone, strength, spasticity; has to make sure everyone can use. Need statement: a method to maintain hand grip on rackets in sports for individuals with impaired hand grip: easy to adjust, ability to wheel, customizable.
