Nervous System 1 Flashcards
Congenital defect in the spinal column in which the spinal cord and meninges herniate outside the body some forms include meningocele and meningomyelocele
Spina bifida
Dyslexia
Disorder of reading, writing and learning
Syncopal
Pertaining to fainting
Loss of mental capacity
Dementia
Stroke can be caused by cerebral aneurysm, thrombosis, or hemorrhage
Cerebrovascular accident (cva)
Collection of blood within the meninges layer
Subdural hematoma
Paralysis Of four extremities
Quadriplegia
Degeneration of nerve cells that produce de Pauline in the brain, causing tremors muscle weakness, slow movement shovelling gait
Parkinson disease
Inability to speak
Aphasia
A network of interlacing nerve fibres in the peripheral nervous system
Plexus
Collection of nerve cell bodies in the PNS
Ganglion
Capillaries the let certain substances enter the brain and keep other substances out
Blood-brain barrier
Elevation in the surface of the cerebral cortex
Gyrus
Depression or groove in the surface of the cerebral cortex
Sulcus
Carries messages toward the brain from receptors; afferent
Sensor nerve
Innermost meningeal membrane
Pia mater
Space in the meninges that contains cerebrospinal fluid
Subarachnoid space
Posterior part of brain that coordinates voluntary muscle movements and maintains balance
Cerebellum
Part of the brain connecting spinal cord to brain, nervous fibres cross here, regulate heartbeat, blood vessel size, and breathing
Medulla oblongata
Largest part of the brain, responsible for muscle activity, thoughts, memory, and senses
Cerebrum
Nervous tissue within spinal cavity and surrounded by backbone from which spinal nerves emerge
Spinal cord
Collection of spinal nerves below the end of the spinal cord; tail end of the spinal cord
Cauda equina
12 pairs of nerves that carry voluntary messages from the brain to/from the head and neck
Cranial nerves
- Pairs of nerves that carry voluntary messages to/ from the spinal cord.
Spinal nerve
Nerves that control, involuntary body functions of muscles, glands, and internal organs
Autonomic nerves
Highly malignant brain tumour of immature, glial cells
Gliiblastoma multiforme
Major convulsive epileptic seizure
Tonic-clonic seizure
Minor form of epileptic, seizure, clouding of consciousness
Absence seizure
Fleeting episode of ischaemia holding back of blood mini stroke
Transient ischaemic attack
Tumour of the meninges; usually benign
Meningioma
Within the meninges
Intrathecal
Space between nerve cells through which nervous impulses travel
Synapse
Part of the brain anterior to the cerebellum; bridging the medulla with the rest of the mid brain
Pons
Painting
Syncope
