Assessing Neurologic System Flashcards
The rendered coordinating and regulating of all body functions
Assessing Neurologic System
The focus on the Central Nervous System and Peripheral Nervous System
Structure and Function
Levels of Consciousness
Coherent
Confused
Lethargic
Obtunded
Unresponsive
Encompasses the brain and the spinal cord
Central Nervous System
Layers of connective tissues
Meninges
Surrounds the brain and spinal cord
Subarachnoid Space
Relies overall filling
Cerebrospinal Fluid
Does electrical activities
Neurons
Located in the cranial cavity
Brain
Four Major Divisions of the Brain
Cerebrum
Diencephalon
Brain Stem
Cerebellum
Largest part of the Brain
Cerebrum
Divisions of the Cerebrum
Right Cerebral Hemisphere
Left Cerebral Hemisphere
Joined bundle of nerve fibers responsible for communication
Corpus Callosum
Impulses sent and received
Cerebral Hemispheres
Four Lobes of the Brain
Frontal Lobe
Parietal Lobe
Temporal Lobe
Occipital Lobe
Intends higher level functions
Gray Matter
Formation of Cerebral Cortex
Rim Surface
Lies beneath the Cerebral Hemispheres
Diencephalon
Responsible for screening and directing the impulses to the specific areas of the Cerebral Cortex
Thalamus
Responsible for regulating many body functions as water balance, appetite, vital signs, sleep cycles, pain perception, and emotional status
Hypothalamus
Located between the Cerebral Cortex and spinal cord
Brain Stem
Composition of the Brain Stem
Midbrain
Pons
Medulla Oblongata
Relay center for ear, eye reflexes, and impulses between the higher cerebral centers
Midbrain
Links the Cerebellum and Cerebrum upon various reflex actions
Pons
Supposes regulation of respiratory function, heart rate and force, and blood pressure
Medulla Oblongata
Located behind the Brain Stem and under the Cerebrum
Cerebellum
Located in the vertebral canal and extends from the Medulla Oblongata to the first lumbar vertebra
Spinal Cord
Has H-shaped appearance
Inner Part
Made up of white matter
Outer Part
Travels the impulses
