To summarize: The nerve pathways involved in equilibrium. Concept introduction: The awareness and monitoring of the head position refer to equilibrium. The brain receives the sensory inputs sent by the sensory receptors. The sensory input from vestibular apparatus, visual sensory input, and the proprioceptor sensory input integrates with each other to balance the equilibrium. During static equilibrium, the utricle and saccule detect the stationary position of the head. For example, when one person is standing straight, the utricle and saccule inform the brain that the head is at an upright position. The utricle and saccule detect the linear acceleration of the head. In contrast, the semicircular ducts are responsible for detection of angular acceleration of the head.

Question

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
