Glossary of 420

- Ignorance of presence of disease - specifically paralysis of a limb resulting in denial of ownership or the limb. Also applies to general inability to perceive disease (ie mental illness).
- inability to WRITE in the ABSENCE of PARALYSIS, COGNITIVE INTENT. Language related.
- Inability to READ
- Receptive Aphasia
- Inability to understand spoken language. Wernickes - 22,39
- Global Aphasia
- Combined inability to express and to understand spoken language.
- Ideational Apraxia (agnosia)
- MISUSE of objects due to MIS-IDENTIFICATION. Ie use fork to comb hair.
- Verbal Apraxia
- Inability to produce motor patterns resulting in speech - WITHOUT impaired understanding, muscle paralysis/weakness or intellect
- Motor Apraxia
- Disorder of VOLUNTARY mvmt not withstanding the absence of paralysis or muscle weakness.
- Inability to perform purposeful mvmts in the absence of paralysis/weakness.
loss of the ability to execute or carry out learned purposeful movements, despite having the desire and the physical ability to perform the movements. It is a disorder of motor planning.
- Constructional apraxia
- Inability to draw objects in the absence of paralysis.
- Asterognosis (tactile agnosia)
- Inability to identify held objects in the absence of language or sensory loss.
- IMPAIRMENT OF MOTOR FUNCTION of SPEECH PRODUCTION
- Impairment of SWALLOWING
- Impairment in PROCESSING OF LANGUAGE.
- Neglect of motor function of one side of the body - usually left b/c right brain is dominant for fx of body awareness.
- Neglect of SENSORY and therefore awareness of one side of the body.
Usually left (because right is dominant for body awareness). MCA is usually lesion.
- Neglect of one side of the body - arising from BODY IMAGE DYSFX
- partial paralysis of one side of the body (not just weakness)
- Paralysis of one side of the body
- Motion sense
- Info from specific sensory receptors in jts, tendons and muscles
- Growth in number of cells by cell division (mitosis)
- Whoe cell mvmt, cell crawling
- Special surface receptors adhere cells to one another to form multi-cellular structures
- Cells become committed and begin to specialize
- Growth & Remodelling
- Differentiated cell can GROW in size, but not number.
REMODELLING via selective programmed cell death
- Vascularization and nutrition
- Blood vessels develop (angiogenesis) to supply the tissue and...
Secretion of nutritional CSF by ependymal cells of choroid plexus
**NO lymphatic system in brain tissue!**
- Covering of axons (not dendrites of cell bodies) by wrapping of myelin.
CNS - oligodendrocytes
PNS - Schwann Cells
- Cell death
- Apoptosis - programmed cell death, restricted by blockers. Impt role in pruning unwanted neurons during neural development
- Support & Coverings
- NO CT in brain tissue (ie no fibroblasts), BUT is support cells and CT associated w/ blood vessels. And CT containing coverings.
- Acute pain
- Unpleasant sensory perceptual or emotional response to an ACTUAL noxious stimulation of a tissue or an organ.
- Sensation of the pain in response to normally NON-PAINFUL stimuli
- Absence of pain in response to stimulus that is not normally painful
- Absence of ALL sensory modalities
- Pain in a joint
- Benign Pain
- Pain that persists with NO KNOWN nocioceptive input from periphery
- BURNING pain
- Chronic Pain
- Pain that persists for longer than a month beyond usual course of acute injury/disease
- DEafferentiation of pain
- pain due to loss of sensation of afferent fibers. Phantom limb pain?
- UNpleasant abnormal sensation (not usually pain)
- Lessened sensitivity to painful stimulus
- Diminished sensitivity to any sensory stimulus
- Impaired fx of a nerve
- UNpleasant sensory and emotional experience associated with actual or potential tissue damage
- Pain in distribution of sensory nerve root(s)
- Abnormal sensation, not unpleasant.
- involvement of NERVE ROOTS
- Motor Unit
- A single alpha motor neuron and all the muscle fiberS it innervates.
- PAttern of nervous system responses
