Gyri gyrus - Study guides, Class notes & Summaries

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 does the thalamus do? - 1. relay station (receives info and tells it where to go) 2. receives sensory fibers from optic tract, ears, and spinal cord 3. receives motor info from cerebellum 4. projects fibers to the cerebrum 5. receives messages from all the sensory receptors and relays it to the proper part of the cerebrum What does the cerebellum do? - 1. coordinates movement and balance 2. processes sensory info and receives input from muscles 3. associated with ataxia (uncoordinate...

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...

Stimulus input --> integration, perception, decision making, and coordination --> response output The Brains 3 Primary Functions 1. Creating a sensory reality 2. Integration Info 3. Producing Behavior The Brains Primary Functions: Creating a sensory reality evolution has equipped each species with a view of the world hat helps it survive; ex: bees can see UV rays, snakes have heat sensing, dogs with smell, etc. The Brains Primary Functions: Integration Info curre...

telencephalic hemispheres (cerebral hemispheres) are separated by - ANSWER-longitudinal fissure (aka interhemispheric fissue) what attaches the cerebellum to the posterior aspect of the brainstem? - ANSWER-cerebellar peduncles what area of the brain do some people consider a lobe? - ANSWER-insula which gyrus extends onto the medial surface of the brain and is half of the paracentral lobule - ANSWER-precentral gyrus - which represents most of the primary motor cortex where do 40% of...
