What are the difference between the different senses of touch? Define vestibular, kinesthetic, and cutaneous sense. How does kinesthetic sense work? What are some common sensory disorders related to touch?
Vestibular Sense Structures of the inner ear that registers the orientation of the head Kinesthetic Sense Ability to perceive extent, direction, or weight of movement Cutaneous Sense Faculty by which external objects or forces are perceived through contact with the body
Inner ear The semicircular canals and cochlea Form the organs of balance and hearing Embedded in the temporal bone Semicircular canals Three fluid-filled bony channels in the inner ear Utricle A small cell, sac, or bladder like protuberance in an animal or plant Somatosensory (sensory) cortex A brain region that processes information coming from the muscles, joints, and skin
What is it? The sense that detects bodily position, weight, or movement of the muscles, tendons, and joints Interlaces with Proprioception Examples Falling Raising your hand Kicking a ball Phantom Limb Sensation Sensation that an amputated or missing limb (even an organ, like the appendix) is still attached to the body and is moving appropriately with other body parts
Pain A feeling of marked discomfort in a particular part of the body Physical suffering or discomfort caused by illness or injury Body’s adaptive response to conditions that threaten your body Control theory A theory which sees crime as the outcome of an imbalance between impulses towards criminal activity and controls which deter it Cutaneous receptors Sensory receptor found in the dermis or epidermis Part of the somatosensory system Include e.g. cutaneous mechanoreceptors, nociceptors (pain) and thermoreceptors (temperature)
Gate control theory Proposes pain is modulated by a spinal gate that determines whether a pain signal is allowed to go on to the brain. Mechanoreceptors A sense organ or cell that responds to mechanical stimuli such as touch or sound Thermoreceptors a sensory receptor that responds to heat and cold Nocioreceptors responds to potentially damaging stimuli by sending nerve signals to the spinal cord and brain
Acupuncture System of complementary medicine that involves pricking the skin or tissues with needles Used to alleviate pain and to treat various physical, mental, and emotional conditions. Lamaze method Method that prepares a mother for natural childbirth Pregnant woman (in classes and at home) practices (usually with the help of a coach) and learns about the physiology of: Childbirth Techniques of relaxation Concentration And breathing
Congenial Insensitivity to Pain Connection between nerves that sense pain and brain’s recognition of pain is missing so people cannot feel pain http://www.youtube.com/watch?v=6-Gd-pG-cDI Sensory Processing Disorder Condition that exists when sensory signals don’t get organized into appropriate responses
