COMD 4500 - Exam 1
Where do SLP's work? - ANS 59% in education, 39% in healthcare.
school systems, hospitals, clinics, rehabilitation centers, nursing homes, home health
A multidisciplinary team may consist of - ANS physician, nurses, PT, OT, RT, dietitian,
psychologist
ASHA Code of Ethics - ANS Principle of Ethics I:
Individuals shall honor their responsibility to hold paramount the welfare of persons they serve
professionally
Principal of Ethics II: maintain highest level of professional competence and performance
Principal of Ethics III: advocating for the unmet communication and swallowing needs of the
public... provide accurate information
Principal of Ethics IV: uphold the dignity and autonomy of the professions... harmonious
interprofessional and intraprofessional relationships
Durable Power of Attorney - ANS proxy for patients that can not make decisions.
- knows patients wishes
- accept or refuse specific treatment
- decide on life saving measures
-
Living Will - ANS A document prepared by the patient when they can make decisions on their
own. outlines what measures are acceptable (DNR, nutrition, hydration, ventilation). Enforced
when the patient is unable to make decisions but overruled when the patient is able to state
wishes at that time.
How many neurons in the brain? - ANS 100 billion in the brain
Neurons are supported by - ANS glial cells
Neurons are bathed in - ANS CSF
Neurons need - ANS constant oxygen and glucose
loss of myelin - ANS disrupts signal transmission
Nerve impulses - resting potential - ANS when cell is at rest
Nerve impulses - excitation - ANS brings target neuron closer to threshold
, Nerve impulses - inhibition - ANS takes target neuron farther from threshold
action potential - ANS an all or nothing electrochemical event
refractory period - ANS recovering from action potential
synapse - ANS A junction where information is transmitted from one neuron to the next.
Neurotransmitters released. Drugs can affect neurotransmitters.
Central Nervous System - ANS Brain and Spinal Cord
gray matter for processing signals
White matter surrounds axons connecting neurons
protected by the meninges
CSF
Blood Brain barrier
Frontal lobe - ANS voluntary movement, cognition
Temporal lobe - ANS hearing, memory processing
Parietal lobe - ANS sense of taste, touch, movement
Occipital lobe - ANS vision
Brainstem - ANS midbrain -
pons-
medulla -
Spinal Reflex - ANS auto reaction to sensory input with local processing and moor output.
Rapid response. You can slightly override.
CSF - ANS nourishes and protects the brain, drains metabolic waste
Peripheral Nervous System - ANS sensory input from periphery
motor output to muscles
Spinal nerves for trunk and limbs
cranial nerves for head and neck
Cranial Nerves - ANS 12 pairs of nerves that carry messages to and from the brain
Direct Activation Pathway - ANS The pyramidal system. Causes voluntary movement.
Corticobulbar tract - leads to cranial nerves, head and neck muscles, controls larynx and
articulators
