Important things that you should know Flashcards
Define tone
tone is the state of contraction in the muscles at rest
- so normal muscles are floppy at rest
what kind of lesion is increased muscle tone
UMN lesion
what kind of lesion is decreased muscle tone
LMS lesion
what is clonus
- it is associated with UMN lesions involving descending motor pathways
- it is a series of involuntary rhythmic muscular contractions and relaxation
what is fascinations
this is a brief spontaneous contraction affecting a small number of muscle fibres, this often causes a flicker of movement under the skin
describe Lower motor neurone lesions
- loss of alpha motor neurone or peripheral nerve
- decreased tone
- decreased reflexes
- leads to muscle wasting
- fasciculation - the spontaneous contraction of denervated muscle
describe upper motor neurone weakness
- loss of descending control
- increased tone and clonus
- increased reflexes
- abnormal reflexes
what is the cause of clubbing and what diseases does it occur in
- the amount of soft tissue beneath the nail bed increases
- it occurs in disorders such as lung cancer, lung abscess, pulmonary fibrosis and some ongeitnal heart disorders and liver disorders
what are the common symptoms of clubbing
- nail beds soften - nails seem to float instead of being firmly attached
- nails form a sharper angle with the cuticle
- last part of the finger may appear larger or bulging and it may also be warm and red
- nail curves downwards so it looks like the round part of an upside down spoon
why do you check the lymph nodes in a respiratory examination
cervical lymph nodes for evidence of metastatic disease
why do you check the apex beat in a respiratory examination
cor pulmonale - this is abnormal enlargement of the right side of the heart as a result of disease of the lungs or the pulmonary blood vessels
what does chest expansion check for
lung collapse or pneumonia
what is muscle wasting a sign of
nerve damage
what can cause the temperature change in an joint examination
cellulitis
inflammatory arthritis
why do you hold the joint as they are moving it
crepitus - creaking at the joint
