What clients are rehabilitated for communication disorders?
Patients who already have language skills (typically older adults)
The order of structures in a neuron (peripheral nervous system):
- dendrites
- nucleus
- soma
- axon
- myelin sheath
- Schwann cell
- node of Ranvier
- …
axon terminal
Cell bodies in neurons are considered _ matter
grey
Axons in neurons are considered _ matter
white
Fibre tracts a.k.a.
axons
Fibre tracts can range from 1 mm to _
1 m long
Between the axons are covered with myelin sheath, and are separated by
Nodes of Ranvier
_ control myelination in the peripheral n ervous system
Schwann cells
control myelination in the central nervous system
oligodendrocytes
Action potentials are _ signals
electrochemical
_ nerves move from the central nervous system, whereas _ nerves move to the central nervous system
Efferent/motor move from, afferent/perception move to
The hemispheres and lobes are a part of the
cerebrum
The reticular formation is involved with _
levels of alertness and consciousness
The reticular formation is a structure located in the
brain stem
The _ is involved with coordination of movement, motor learning, posture, and other aspects not completely known
cerebellum
According to Donald Hebb, _ that wire together, fire together
neural circuits
Action potentials tend to skip across axons, in a _ fashion
saltatory
The _ fibres connect lobes to other lobes
association
Neural development is mediated by
genetics
Newborn neurons develop mostly _ birth (location and connectivity determined _)
before birth;
determined in utero
Neural development continues after birth. True or false?
True
Considering the example of a family of multilinguists with an advanced Perisylvian fissure, this aspect of their neurology would be explained due to their _
neural development
According to the _ syndrome, seizures are due to the environment, whether from hot weather, fever, etc.
Dravet
Neural changes are due to external stimuli/sensory, according to the _ aspect of neurology
neuroplasticity
