Sensory receptors in the skin (cutaneous receptors) are generally of the mechanoreceptor, nociceptor, and thermoreceptor types. Mechanoreceptors sense pressure (such as touch) and vibrations and for example include Meissner corpuscles, Merkel disks, Ruffini corpuscles and Pacinian corpuscles. Nociceptors sense pain caused by damage. Thermoreceptors convey feelings of heat or cold. Chemoreceptors that sense the presence of specific chemicals are sometimes present depending on location but are generally not found on exposed skin.

Is the dermis rich in blood vessels and nerve fibers?
Yes, the dermis is rich in blood vessels (when you itch or scratch your skin and it turns red) and the dermis is rich in nerve fibers because of when you touch your skin you can feel it. TRUE
Nerve fibers in the skin are associated with what?
smooth mucles? blood vessels? sensory nerve endings? hair follicles? all of the above?
What does the dermis contain to communicate with other organs?
The skin is the organ that contains the dermis.
What are pain sensations in the skin muscles tendons and joints that are carried on large nerve fibers?
somatic pain
What types of cells does a sea turtle have?
They have many that we have: skin cells, muscle cells, brain cells, nerve cells. and bone cells.
What is the clinical importance of cremestric muscle reflex?
Well you can asses the function of ilioingunial nerve and genitofemoral nerve. Cremasteric relfex can be demonstarted by lightly touching the skin of the upper medial thigh, resulting in a slight elevation of the testis. The sensory fibers of the reflex are carried by the L1 fibers of the Ilioinguinal nerve and the motor response is a functional of the genital branch of the genitofemoral nerve that innervates the cremastric muscle.
What are the two types of receptors in the skin that detect fine touch?
There are not tow types of sensory receptors in the skin there are many types of sensory receptors in the skin i.e., in the CUTANEOUS RECEPTORS of the MECHANORECEPTORS. They are the: Meissner's corpuscles, Merkel's disc, Paccinian corpuscles, Ruffini's end organs, Free Nerve Endings and Hari Follicel Organs.
How many types of mechnoreceptors are there?
6 in total. 4 are found on glaborous skin with specalised nerve endings (Meissner's Merkel's, Paccinian, Ruffini) Unspecialised mechanoreceptors that have free nerve endings Hair follicle cells
Are nerves present skin?
The skin has nerves to detect changes in the external environment. The nerves of the skin can detect heat and cold, pressure, pain, and touch.
CAN reflex action controlled by spinal cord?
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.
Which two types of tissue present in skin?
Nerve tissue and Epithelial tissue would be my guess. But I am no expert, just a homeschooling mom.
What is the nerve of the skin?
trigemenal nerve
