What is sensory radiculopathy?

Radiculopathy is defined as pain and/or neurologic deficit in a specific nerve root distribution, including motor loss, sensory changes, and sometimes depression of reflexes.

What are the 3 main parts of the spinal cord?

The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.

What is the difference between radiculopathy and radicular pain?

Radiculopathy can be defined as the whole complex of symptoms that can arise from nerve root pathology, including anesthesia, paresthesia, hypoesthesia, motor loss and pain. Radicular pain and nerve root pain can be defined as a single symptom (pain) that can arise from one or more spinal nerve roots.

What are radicular signs?

Radicular syndrome results in pain and other symptoms such as numbness, tingling and weakness in the arms or legs. It is caused by compressed or irritated nerve roots. The nerve roots are branches of the spinal cord that carry nerve signals out to the rest of the body at each level along the spine.

What does radicular pain feel like?

Radicular pain is a type of pain that radiates from your back and hip into your legs through the spine. The pain travels along the spinal nerve root. The leg pain can be accompanied by numbness, tingling, and muscle weakness. Radicular pain occurs when the spinal nerve gets compressed (pinched) or inflamed.

What part of your spine controls your legs?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

What is the function of nerve?

A nerve is a bundle of fibers that receives and sends messages between the body and the brain. The messages are sent by chemical and electrical changes in the cells, technically called neurons, that make up the nerves.

How many spinal cords are in the human body?

The cord is segmentally organized. There are 31 segments, defined by 31 pairs of nerves exiting the cord. These nerves are divided into 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal nerve (Figure 3.2).

Where are sensory and motor axons located in the spinal cord?

Spinal nerves transmit sensory and motor information between the spinal cord and the rest of the body. Each of the 31 spinal nerves (in humans) contains both sensory and motor axons.

How are sensory and motor processes related to each other?

• The detection and processing of sensory information and the generation of motor output provide the physiological basis for all animal activity. Concept 50.1 Sensory receptors transduce stimulus energy and transmit signals to the central nervous system • All sensory processes begin with stimuli, and all stimuli represent forms of energy.

Why are sensory studies used in motor and reflex examination?

The sensory studies should always be used within the context of the motor and reflex examination as well. The extent of the sensory testing employed should usually be based on the context of the other examination findings. Sensory deficits can occur as a result of CNS or peripheral nerve system injuries.

What are the primary and secondary modalities of sensory function?

Sensory function can be divided clinically into primary and secondary (aka cortical) modalities. Primary modalities include light touch, pressure, pain, temperature, proprioception, and vibration sense. Cortical modalities require the synthesis and integration of the input from the primary modalities.
