Other senses : แบบฝึกหัด

Which of the following sensations are detected by specialised sensory cells in our skin?

The skin is recognized as a sense organ containing specialized sensory cells. Which of the following senses is NOT primarily detected by the sensory cells present in the skin?

An experiment is conducted to demonstrate the unreliability of the skin's temperature perception. A student places their left hand into iced water ( very cold ) and their right hand into warm water ( very hot ) for two minutes. Subsequently, both hands are immediately placed into a bucket of lukewarm water. What sensation will the student most likely perceive in their hands, and why?

The sense of balance (equilibrium) is essential for movement and posture. The sensory information crucial for detecting changes in the head's rotational movements is primarily gathered by which specific structures in the inner ear?

Different parts of our limbs, such as the fingertips and the forearm, show different levels of sensitivity to touch. Explain why these areas differ in their ability to detect stimuli.

Explain how motion sickness occurs in a virtual reality (VR) experience where the user is physically stationary but visually perceives rapid movement, identifying the specific sensory conflict that causes this disorientation.

The human ability to maintain balance and coordinate movement is a complex function involving the continuous integration of sensory information by the brain.

a) Identify the three primary sensory systems that provide the brain with inputs necessary to maintain the body's sense of balance. For each system, state the specific sensory structure or organ responsible for gathering the information. (3 points)

b) Stand-up paddleboarding (SUP) requires intense balance and coordination. Explain how sensory integration occurs when a beginner is trying to balance on a moving SUP board in choppy water. Furthermore, describe what happens if the inputs from two of these systems conflict (e.g., visual input suggests stability while inputs from the inner ear suggest movement), and explain the typical response the brain produces.
