10 CNS, Spinal Nerves And Cranial Nerves Flashcards
What are spinal meninges?
Meninges are connective tissue coverings that surround the brain and spinal cord.
The spinal cord extends from the base of the __ to the superior border of the second lumbar vertebra.
Skull
The spinal cord conducts nerve impulses along tracts and serves as an __ centre for spinal reflexes.
Integrating
3 layers of connective tissue wrappings protect axons; __ surrounds individual axons, __ surrounds bundles of axons, and __ surrounds an entire nerve.
Endoneurium; perineurium; epineurium
A __ is a fast, involuntary sequence of actions that occurs in response to a particular stimulus.
Reflex
The __ __ consists of the medulla oblongata, pons, and midbrain.
Brain stem
The __ connects the pons to the diencephalon.
Midbrain
The __ is the principal relay station for sensory impulses that reach the cerebral cortex from other parts of the brain and the spinal cord.
Thalamus
The __ provides us with the ability to read, wrote, and speak; make calculations and compose music; remember the past and make future plans; and create.
Cerebrum
The __ system governs emotional aspects of behaviour.
Limbic
Particular areas of the __ __ process sensory, motor, and integrative signals.
Cerebral cortex
Nerve impulses for somatic sensations conduct to the primary somatosensory area in the postcentral gyrus of the __ __.
Cerebral cortex
__ motor neurons stimulate skeletal muscles to produce movements.
