EMBRYONIC DEVELOPMENT OF THE NERVOUS SYSTEM  General Embryonic Development is Described as Either:  Trimesters (3x 3-Month Periods): o First: - Foundations of Major Organs o Second: - Development of Organs o Third: - Rapid Growth & Fully Functional Organs.  OR... Anatomical Stages: **(These are more relevant) o Pre-Embryonic Period: 0-2 Weeks  Fertilisation  Blastocyst Formation & Implantation  Gastrulation o Embryonic Period: 3-8 Weeks  Development & Differentia...

Gyri/ gyrus Correct Answer elevated ridges "winding" around the brain Sulci/ sulcus Correct Answer small grooves dividing the gyri Central Sulcus Correct Answer divides the Frontal Lobe from the Parietal Lobe Fissures Correct Answer deep grooves, generally dividing lobes of the brain Longitudinal fissure Correct Answer divides the two cerebral Hemispheres Sylvian/ Lateral Fissure Correct Answer Divides the temporal Lobe from the Frontal and Parietal Lobes Transverse Fissure C...

Neuro SCNM Question and answers correctly solved 2023/2024Cerebral Edema (vasogenic, cytotoxic hydrocephalic) - correct answer There are three kinds: Brain is softer, gyri are flattened, sulci are narrowed, and ventricular cavities are compressed escapes from the blood vessels into the intercellular space of the brain. Localized (abscesses, neoplasms), or generalized ase in intracellular fluid secondary to cellular injury (generalized hypoxic/ischemic insult) from the intraventricular CSF...

Neuro SCNMCerebral Edema (vasogenic, cytotoxic hydrocephalic) - correct answer There are three kinds: Brain is softer, gyri are flattened, sulci are narrowed, and ventricular cavities are compressed escapes from the blood vessels into the intercellular space of the brain. Localized (abscesses, neoplasms), or generalized ase in intracellular fluid secondary to cellular injury (generalized hypoxic/ischemic insult) from the intraventricular CSF flows to the periventricular white matter durin...

The meninges, meaning membranes, are the outer coverings of these structures correct answer: Brain, spinal cord, and proximal nerve roots The three tissue layers enveloping the brain correct answer: 1) Dura Mater-outermost layer, strongest and thickest 2) Arachnoid Mater - thin membrane enclosers the subarachnoid space 3) Pia Mater - innermost layer, follows contour of cortex, composed of 2 layers highly vascular and sheaths blood vessels as they enter brain CSF filled pace between the...

A&P 1 - Brain A& P 1 Chamberlain College Of Nursing - Question and answers 100% correct 2024 A&P 1 - Brain 3 meninges of the brain - correct answer pia mater (cortical surface), arachnoid (middle), and dura mater (outermost layer) -- (PAD) cerebrospinal fluid (CSF) - correct answer circulates between the pia mater and the arachnoid in the subarachnoid space, and circulates inside the cavities of the brain (ventricles) 4 regions of the brain - correct answer cerebrum, cerebellum, ...

Cerebral Hemispheres - ANSWER-L&R Sulci - ANSWER-indentations Lateral, longitudinal, central Lateral Sulcus - ANSWER-divides frontal & patients lobes from temporal lobe Longitudinal Sulcus - ANSWER-separates L&R hemispheres Central Sulcus - ANSWER-separates frontal & parietal lobes landmark used to identify the primary motor & somatosensory cortexes Gyri - ANSWER-bulges or folds in cerebral hemispheres pre & postcentral Precentral Gyrus - ANSWER-aka Primary Motor Corte...

Central Nervous System Correct Answer - composed of the brain and spinal cord Peripheral Nervous System Correct Answer - the pathway that runs to and from the CNS - afferent fibers run toward the CNS; efferent fibers run away from the CNS - composed of: 1) Somatic Nervous System - controls voluntary movements of the striated muscles 2) Autonomic Nervous System - involuntary movements of the smooth muscles, 2 parts: a) Sympathetic nervous system - arousal b) Parasympathetic nervous syste...

what is the main function of the limbic system - emotionally significant stimuli activate SENSORY pathways that trigger the HYPOTHALAMUS to modulate the ANS response (heart rate, blood pressure...) - accumpanying ANS changes to emotional response (amygdala → hippocampus → fornix) - information about emotionally significant stimuli also conveyed to the cortex directly (from hypothalamus) and indirectly (via cingulate) to integrate a motor response to these stimuli - memory and learning als...
