Myotome

hybridization was used to compare Scx in progenitor cells, Pax1 in sclerotome, and MyoD in myotome. Scx expression was restricted to the anterior and posterior borders while MyoD expression was present in the center of the myotome with no overlap of the two markers. When Scx was compared to Pax1 it appeared that they existed in the same region; however, Pax1 was expressed more ventromedial and Scx was closer to the myotome, these markers did not have any overlap either. Additionally, Scx expression occurred

between the myotome layers, indicating they arose from both chick and quail cells. While transplanted quail and host chick sclerotome indicated that the Scx expressing cells were entirely produced by quail cells. This observation suggested that Scx expressing cells between two layers of myotome form from the anterior and posterior edges to two adjacent somites. On the other hand, two adjacent dermomyotome layers did not produce any Scx expressing tendon progenitors but, it did produce myotome and dermotome

Myotomes are spinal nerve fibers and the corresponding muscles. When a spinal cord injury happens, myotomes can be damaged which result in the lack of movement in a muscle and the abnormal functioning of dermatomes can pinpoint spinal nerve damage because lack of sensation occurs. 6. Define the term

the chest. 5. Define the terms dermatome and myotome and explain how each relates to SCI. Spinal nerves have motor fibers and sensory fibers. The motor fibers innervate certain muscles, while the sensory fibers innervate certain areas of skin. A skin area innervated by the sensory fibers of a single nerve root is known as a dermatome. A group of muscles primarily innervated by the motor fibers of a single nerve root is known as a myotome. Myotomes are necessary for proper motor functioning; making

Intro: Tuberculosis (TB) Spondylitis, also known as Pott’s Disease, is often a result of an extra-spinal infection. Pott’s disease can occur as a combination of arthritis and osteomyelitis and often involves more than 1 vertebrae. The anterior most portion of the vertebrae is commonly affected. The TB infection of one vertebrae may spread to surrounding vertebrae and vertebral discs causing a further secondary infection. (Enarson 294-296) Epidemiology: Pott’s disease is one of the oldest diseases

altered motor or sensory function that do not correspond to a recognized neurologic pattern or syndrome, with an onset related to a major psychological stressor. In this case, the symptoms of right foot and left hand weakness do not correspond to a myotome, and the patient exhibits contradictory examination findings (e.g. diminished foot dorsiflexion on the exam table, but absence of foot drop on ambulation). She recently had a major psychologic stress in being diagnosed with Crohn disease. Conversion

there is improved and now painless range of motion. There is full sensation to light touch in the hand. The only deficit noted is an inability to abduct the shoulder. Which of the following includes the most likely responsible muscle, nerve, and myotome? A. Biceps brachii muscle, musculocutaneous nerve, C6 B. Deltoid muscle, axillary nerve, C4 nerve root C. Deltoid muscle, axillary nerve, C5 nerve root D. Supraspinatus muscle, suprascapular nerve, C6 nerve root E. Teres minor (muscle),

joints above and below were tested with decrease in ROM detected. ROM at the shoulder was examined with decrease in flexion of the glenohumeral joint and decrease in the range of medial rotation of right shoulder. On carrying out of special tests, Myotomes were positive for triceps weakness and dermatomes were positive for tingling at C6 level on right. Upper limb tension tests (ULTTs) were carried out with ULTT1 and ULTT2a positive due to pins and needle

Alex Fulton Histology Dr. Morris October 20, 2015 Short Case Study: Spinal Cord A 21 year old male patient was taken to the hospital after being involved in a one vehicle-motorcycle accident. The individual complained of pain in his lower back and suffered numerous abrasions and contusions along with loss of sensation and motor control in his legs. A complete neurological exam was performed in order to fully assess the patient. The exam revealed that the patient demonstrated nearly normal to normal

1) Explain how each of the five elements of the patient/client management model are integrated into this case study. (15 points) The five elements of the patient/client management model are the examination, evaluation, diagnosis, prognosis, and interventions, with patient outcomes being continuously measured. Examination: During the initial examination the physical therapist is trying to gather information through patient interview and test and measures to help determine a plan of care for the
