What is an a sclerotome?
A sclerotome is a deep somatic track that is innervated by the same signal spinal nerve and when the tissue of a sclerotome is irritated by mechanical or chemical stimuli pain is "experienced" as originating from all of the tissues that are innervated by the same nerve, or along the sclerotome. Chart shows spinal levels C-1 through S-3.
What is sclerotomal pain?
Sclerotomal pain is deep bone pain referred from specific vertebral segments that may be interpreted as non-physiological. Bone pain may be either local or referred from ipsilateral spinal segments. Click to see full answer.

Sclerotogenous pain is reported by patients as deep, ill defined, dull aching, and diffuse. Sclerotogenous pain does not follow dermatomes but does follow a sclerotome pain pattern.
Does sclerotogenous pain follow dermatomes?
Sclerotogenous pain does not follow dermatomes but does follow a sclerotome pain pattern. The tissues that are included in sclerotogenous pain include: Ligaments, Tendons, Discs, Periosteum and Apophyseal Joints.
What causes Sclerotome pain?
Pain from bony, ligamentous and fascial structures innervated by the same single spinal nerve root is referred to as sclerotome pain. It is the type of deep pain felt from a pathological bone disease such as multiple myeloma or a metastatic tumor. It is also the type of pain felt from sprain of a joint.
What is Sclerotogenous pain?
This is also known as “referred pain”. Sclerotogenous or referred pain, for example, is thought to be the cause of arm and neck pain in a patient experiencing a heart attack. Many structures such as the kidneys, gallbladder and the psoas muscle can refer pain into the low back and hips.
What is Dermatome pain?
This refers to conditions in which a nerve root in the spine is compressed or pinched. Symptoms can include pain, weakness, and tingling sensations. Pain from radiculopathies can follow one or more dermatomes.
What is somatic referred pain?
Somatic referred pain is the most common form of pain that traces back to your spinal structures. It can arise from any structure that contains a nerve supply, such as from inside the disc, the facet joint or the muscles. It does not come from pressure on a spinal nerve.
Where does visceral pain usually start?
Visceral pain occurs when pain receptors in the pelvis, abdomen, chest, or intestines are activated. We experience it when our internal organs and tissues are damaged or injured. Visceral pain is vague, not localized, and not well understood or clearly defined. It often feels like a deep squeeze, pressure, or aching.
What causes dermatome pain?
Dysfunction or damage to a spinal nerve can trigger symptoms in the corresponding dermatome. Nerves damage or dysfunction may result from infection, compression, or traumatic injury. Doctors can sometimes use the severity of symptoms in a dermatome to determine the extent and location of nerve damage.
What is an example of a dermatome?
Examples of dermatomes are as follows: Numbness and tingling down the right arm to the thumb and middle finger may involve C6-C8 dermatomes and indicate abnormalities in the spinal nerves of the C6-C8 nerve roots, whether in the vertebrae, spinal cord, or discs.
Where are dermatomes located?
the spinal cordDermatomes are located in the spinal cord. Myotomes is a group of single spinal nerves that originate from a groups of muscles.
What dermatome means?
A dermatome is an area of skin in which sensory nerves derive from a single spinal nerve root (see the following image). Dermatomes of the head, face, and neck.
What does somatic pain feel like?
Somatic pain can be deep or superficial, with the deeper pain coming from the skeletal structure, tendons, and muscles. It can be described as aching, cramping, gnawing, or even sharp. It usually appears in one area of the body, and movement can trigger it.
What causes somatic dysfunction?
Causes. Somatic dysfunction can be caused by acute or chronic postural deviations or alterations of a body part or region. Most commonly this occurs from sudden movements during a slip or fall, but can also be from biomechanical deviations as well as postural abnormalitites.
Is neuropathic pain somatic?
Both somatic and visceral pain can be nociceptive, neuropathic, or algopathic. The two classification systems have full overlap.
What is the definition of a sclera?
1. an instrument used in incision of the sclera. 2. the area of a bone innervated from a single spinal segment. 3. one of the paired masses of mesenchymal tissue, separated from the ventromedial part of a somite, which develop into vertebrae and ribs. Miller-Keane Encyclopedia and Dictionary of Medicine, Nursing, and Allied Health, Seventh Edition.
What is the term for failure of segmentation between the fourth occipital sclerotome and the
Atlanto-occipital assimilation is failure of segmentation between the fourth occipital sclerotome and the first spinal sclerotome . [17] Dermomyotome also serves as a tissue for secreted signaling molecules to the neural tube, notochord, and sclerotome [13, 14].
What is the cranial portion of the first cervical sclerotome?
reptiles) the cranial half of the first cervical sclerotome remains as a separate bone, 'the proatlas', between the occiput and atlas vertebra. Study of variations of occipital condyles. Vertebrae are derived from the sclerotome portions of the somites, which are derived from paraxial mesoderm.
Where do sclerotomal cells from adjacent somites become merged?
Sclerotomal cells from adjacent somites become merged in intersomitically located masses that are the primordia of the centra of the vertebrae. [ sclero- + G. tomē, a cutting] Medical Dictionary for the Health Professions and Nursing © Farlex 2012.
What is the name of the region of the limb muscle that develops into the dermatome?
Macrodystrophia-giant thumb. Dorsally, somites differentiate into epithelial dermomyotome, which then develops into myotome (the source of limb muscle), into dermatome (a specific region for nerve reception supplied by sensory neurons), and ventrally into mesenchymal sclerotome. The nuclei of myofibers originate from the myotomal somitic ...
What is sclerotogenous pain?
Sclerotogenous pain is reported by patients as deep, ill defined, dull aching, and diffuse. Sclerotogenous pain does not follow dermatomes but does follow a sclerotome pain pattern. The tissues that are included in sclerotogenous pain include: Ligaments, Tendons, Discs, Periosteum and Apophyseal Joints. A sclerotome is a deep somatic track that is ...

Why does my visceral muscle hurt?
Visceral pain can result from mechanical and chemical irritation of an organ. This irritation can include ischemia, acidity and chemical irritation, spasm of visceral muscles, overdistention of a hollow organ due to flatulence, feces, or fluid distention.
