Somatic receptors are a specialized type of receptor located near the surface of the body. These cells detect passive types of environmental stimuli, such as temperature, air currents, and barometric pressure. The receptors transmit the information to the sensory pathways via action potentials. The sensory pathways deliver the somatic (and visceral) information to the central nervous system.

Where are receptors for somatic sensations located?
cerebrum's outer layer of gray matter, the cerebral cortex.
Which component of the nervous system makes contact with the environment?
The somatic nervous system of the peripheral nervous system (PNS) makes contact with the enviroment.
Reflex that control skeletal muscle are called?
Somatic Reflex
What is corneal reflex somatic?
yes it is somatic
What is meant by noriceptive Pain example somatic and visceral?
Nociceptive means having to do with pain. So the phrase "nociceptive pain" is redundant. The body's nervous system has 2 kinds of nociceptive receptors--somatic and visceral. Visceral means having to do with the viscera, which are your hollow internal organs (such as the stomach and the intestines). Whereas somatic pain receptors are easily localized, visceral pain is difficult to pin down as to location. Thus, when you have pain on a particular finger, you know exactly which finger is hurting and where the pain is on the finger. But when you have something wrong with a part of your intestine, and it's the intestine on the right side of your abdomen, the pain is going to seem to be coming from the midline of your abdomen, not on the right side. An example is appendicitis, whose pain is typically felt in the midline until the inflammation reaches the abdominal wall (which is somatic), at which time the pain is felt on the right side of the abdomen.
How are sensory receptors classified?
somatic receptors and special receptors
Normal balance or equilibrium depends on input from a number of sensory receptors name them?
Vestibular receptors, Visual receptors, Somatic receptors (from skin, muscle, joints)Type your answer here...
Are general somatic receptors distributed evenly over the body?
no
Where are receptors for somatic sensations located?
cerebrum's outer layer of gray matter, the cerebral cortex.
What kind of pain comes from a gun shot to the abdomen?
Both somatic and visceral pain. The somatic pain would come from cutaneous receptors and visceral pain from the intestines.
Which component of the nervous system makes contact with the environment?
The somatic nervous system of the peripheral nervous system (PNS) makes contact with the enviroment.
What neurotransmitter control the somatic nervous system and how does it work?
Acetylcholine (ACh) is the only neurotransmitter used in the motor division of the somatic nervous system. It works by binding to acetylcholine receptors on skeletal muscle fibers and opening ligand-gated sodium channels in the cell membrane.

Define a somatic receptor?
Receptors located on the body surface. They transduce/convert environmental energies (e.g. light, heat, pressure) into action potential that are processed by the brain.
What are motor end plates associated with?
Motor end plates are associated with cholinergic receptors. It can be muscarinic if it is innervated by the post ganglionic parasympathetic nervous system. If under sympathetic, it will be innervated by adrenergic receptors (exception being sweat glands). For somatic nervous system it is nicotinic.
Where does the neurons in the primary sensory cortex receive somatic information from?
Most of the sensory information first goes through the thalamus. touch, pressure, pain, taste, and temperature receptors.
What physically causes the trip on LSD?
As simply stated as possible: Lysergic acid diethylamide (LSD) bonds to seven-transmembrane domain receptors associated with nerotranmitters. It bonds easily with all dopamine receptors and subtypes, all adrenoreceptor subtypes, and most serotonin receptors. Activating these receptors in neurotransmitters results in euphoria, the physiological manifestations of LSD use, and can (often does) result in aural, visual, and somatic (kinetic) hallucinations.
