  • Cortex Brainstem Spinal Cord Thalamus Cerebellum Basal Ganglia
    Harvard-MIT Division of Health Sciences and Technology HST.131: Introduction to Neuroscience Course Director: Dr. David Corey Motor Systems I 1 Emad Eskandar, MD Motor Systems I - Muscles & Spinal Cord Introduction Normal motor function requires the coordination of multiple inter-elated areas of the CNS. Understanding the contributions of these areas to generating movements and the disturbances that arise from their pathology are important challenges for the clinician and the scientist. Despite the importance of diseases that cause disorders of movement, the precise function of many of these areas is not completely clear. The main constituents of the motor system are the cortex, basal ganglia, cerebellum, brainstem, and spinal cord. Cortex Basal Ganglia Cerebellum Thalamus Brainstem Spinal Cord In very broad terms, cortical motor areas initiate voluntary movements. The cortex projects to the spinal cord directly, through the corticospinal tract - also known as the pyramidal tract, or indirectly through relay areas in the brain stem. The cortical output is modified by two parallel but separate re­ entrant side loops. One loop involves the basal ganglia while the other loop involves the cerebellum. The final outputs for the entire system are the alpha motor neurons of the spinal cord, also called the Lower Motor Neurons. Cortex: Planning and initiation of voluntary movements and integration of inputs from other brain areas. Basal Ganglia: Enforcement of desired movements and suppression of undesired movements. Cerebellum: Timing and precision of fine movements, adjusting ongoing movements, motor learning of skilled tasks Brain Stem: Control of balance and posture, coordination of head, neck and eye movements, motor outflow of cranial nerves Spinal Cord: Spontaneous reflexes, rhythmic movements, motor outflow to body.

  • Development of the Flexion Withdrawal Reflex
    Spinal sensory processing in the human infant: Development of the flexion withdrawal reflex Laura Louise Cornelissen Thesis submitted for the degree of Doctor of Philosophy University College London 2011 1 Declaration The work in this thesis was conducted in the Department of Neuroscience, Physiology and Pharmacology at University College London, and in the Elizabeth Anderson and Obstetrics Wing at University College Hospital. I, Laura Louise Cornelissen, confirm that the work presented in this thesis is my own. Where other information has been derived from other sources, I confirm that this has been indicated in the thesis. Laura Louise Cornelissen March 2011 2 Abstract Immature spinal sensory reflexes have lower mechanical thresholds and are poorly coordinated and exaggerated compared to adult reflexes. However, little quantitative data is available on how these spinal sensory circuits develop in the human infant. This thesis investigates the development of cutaneous flexion withdrawal reflexes in preterm and full- term human infants following noxious and non-noxious stimulation of the heel, and tests whether flexion withdrawal reflex activity is modulated by the commonly administered analgesic, oral sucrose, in a randomised controlled trial. The studies were undertaken in infants aged 28-45 weeks gestation (GA), in-patients at University College Hospital, London. The noxious stimulus was a clinically required heel lance; non-noxious stimulation was either a light touch of the heel or application of calibrated von Frey hairs to the heel. Flexion withdrawal reflex activity was recorded with surface EMG electrodes placed over the biceps femoris muscle. Video recordings of facial expression were recorded for clinical pain assessment.

Teasdall, MD* Multiple stretch reflexes occur in muscles adjacent to or remote from the tap. The response may be ipsilateral or bilateral. These reflexes are encountered not only in normal subjects with brisk stretch reflexes but particularly in patients with lesions of the upper motor neuron. The concussion obtained by the blow is conducted along bone to muscle. Muscle spindles are stimulated, and in this manner independent stretch reflexes are produced in these muscles. This mechanism is responsible for the phenomenon of multiple stretch reflexes. The thorax and pelvis play important roles in the contralateral responses by transmitting these mechanical events across the midline. (Henry FordHosp Med J 1986;34:31-6) ontraction of muscles remote from the site of f)ercussion is Head and neck Cencountered in patients with brisk stretch reflexes.

  • Deep Tendon Reflexes
    Reflex Physiology Dr. Ali Ebneshahidi © 2009 Ebneshahidi Reflex Physiology . Reflexes are automatic, subconscious response to changes within or outside the body. a. Reflexes maintain homeostasis (autonomic reflexes) – heart rate, breathing rate, blood pressure, and digestion. b. Reflexes also carry out the automatic action of swallowing, sneezing, coughing, and vomiting. c. Reflexes maintain balance & posture. ex. Spinal reflexes – control trunk and limb muscles. d. Brain reflexes – involve reflex center in brain stem. ex. Reflexes for eye movement. © 2009 Ebneshahidi Reflex Arc The reflex arc governs the operation of reflexes. Nerve impulses follow nerve pathways as they travel through the nervous system. The simplest of these pathways, including a few neurons, constitutes a reflex arc. Reflexes whose arc pass through the spinal cord are called spinal reflexes. © 2009 Ebneshahidi Parts of Reflex Arc . 1. Receptor – detects the stimulus. a) Description: the receptor end of a particular dendrite or a specialized receptor cell in a sensory organ. b) function: sensitive to a specific type of internal or external change. 2. sensory neuron – conveys the sensory info. to brain or spinal cord. a. Description: Dendrite, cell body, and axon of a sensory neuron. b. Function: transmit nerve impulses from the receptor into the brain or spinal cord. © 2009 Ebneshahidi Reflex Arc . 3. Interneuron: relay neurons. a. Description: dendrite, cell body, and axon of a neuron within the brain or spinal cord. b. function: serves as processing center, conducts nerve impulses from the sensory neuron to a motor neuron. 4. Motor neuron: conduct motor output to the periphery. a. Description: Dendrite, cell body, and axon of a motor neuron.

  • Coma Deep Tendon Reflexes Definition
    Coma deep tendon reflexes definition Continue The FriendlyCheck printer deep tendon reflexes using pulses from a reflex hammer to stretch muscles and tendons. The limbs should be in a relaxed and symmetrical position, as these factors can affect the reflex amplitude. As in muscle strength testing, it is important to compare each reflex at once with its contralateral counterpart, so that any asymmetry can be detected. If you can't trigger a reflex, you can sometimes deduce it with certain reinforcement procedures. For example, having a patient gently contract muscles are tested by raising the limb very slightly, or their focus on forcibly contracting another muscle group just at the moment when the reflex is being tested. When the reflexes are very lively, the clone is sometimes seen. It is a repetitive vibrational muscle contraction that occurs in response to the muscles and tendon stretch. Deep tendon reflexes are often evaluated according to the following scale: 0: missing reflex 1 : trace, or seen only with reinforcement 2 : normal 3: lively 4 : invulnerable clone (i.e. repetitive vibrational movements) 5 : a steady clone of deep tendon reflexes are normal if they are 1, 2 or 3, if they are not asymistic or there is a sharp difference between the hands and feet. Reflexes rated as 0, 4 or 5 are generally considered abnormal. In addition to the clonus, other signs of hyperreflexion include the spread of reflexes to other muscles not directly tested and crossed the adduction of the opposite leg when the medial aspect of the knee is tapped. 58.

The joint should be supported and Pt. moves the joint against the doctor’s resistance.
