An Introduction to the Human Body, Chapter 2. Put the events of sound wave movement through the ear and nervous pathways in order. -Vitreous humor Light touch, also known as discriminative touch, is a light pressure that allows the location of a stimulus to be pinpointed. There are fewer Pacinian corpuscles and Ruffini endings in skin than there are Merkels disks and Meissners corpuscles. Meissners corpuscles, (shown in Figure3) also known as tactile corpuscles, are found in the upper dermis, but they project into the epidermis. d. cochlear nucleus. - It is a benign tumor - Foliate Mechanical, chemical, or thermal stimuli beyond a set threshold will elicit painful sensations. Osmoreceptors respond to solute concentrations of body fluids. Place the ossicles of the ear in order from the tympanic membrane to the oval window. The modulus of elasticity is 20GPa20 \mathrm{~GPa}20GPa for the concrete and 200GPa200 \mathrm{~GPa}200GPa for the steel. Somatosensation occurs all over the exterior of the body and at some interior locations as well.

Drag each label to the appropriate box to indicate whether each statement is associated with rods or cones. Order the regions of the ear from lateral to medial. Note that these warmth detectors are situated deeper in the skin than are the cold detectors. (Consider that the deep pressure that reaches those deeper receptors would not need to be finely localized.) b. Pigmented layer of retina The Chemical Level of Organization, Chapter 3.

These injuries may result from sports or recreational activities, motor vehicle crashes, falls, physical assaults, and gunshot wounds. Several distinct receptor types form the somatosensory system including thermoreceptors (heat), nociceptors (pain), and mechanoreceptors (pressure). Changes in the external and internal environment are called: Order these structures in the order that the tears travel through them/, 1) Lacrimal puncta Deeper in the dermis, near the base, are Ruffini endings, which are also known as bulbous corpuscles. Merkel's disk are slow-adapting, unencapsulated nerve endings that respond to light touch; they are present in the upper layers of skin that has hair or is glabrous.

The nerves that convey sensory information from the periphery to the CNS are either spinal nerves, connected to the spinal cord, or cranial nerves, connected to the brain. Proprioception and Deep Pressure | Sensory Direct Blog They are found in both glabrous and hairy skin. Some other organisms have receptors that humans lack, such as the heat sensors of snakes, the ultraviolet light sensors of bees, or magnetic receptors in migratory birds.
