X-rays as a type of biomedical imaging does not: allow visualization of internal organs utilize ionizing radiation form a negative image form a 3D image CT scanning: Creates a plane of radiation Can be painful for some people Produces one image to be examined on a computer Allows visualization of soft tissue and internal organs Magnetic resonance imaging: Can be seen as an alternative to X-rays Uses magnetic and radiation frequency to form an image Requires the patient to go into a cylinder that is not a tight fit Uses back projections to reconstruct images
Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
