Study Notes
CNS 1: Brain
- The brain is comprised of the cerebrum, cerebellum, and brainstem.
- Objectives include labeling brain parts and defining their functions, differentiating between cerebellum, cerebrum, and brainstem.
Brain Overview
- Cerebrum: Divided into lobes (frontal, parietal, occipital, temporal).
- Frontal Lobe: Motor functions, executive functions, thinking, smell, speech, emotions.
- Parietal Lobe: Sensory processing, perception, language.
- Occipital Lobe: Visual interpretation.
- Temporal Lobe: Hearing, taste, language comprehension, emotional processing.
- Insula: Gustatory and sensorimotor processing, risk-reward behavior, autonomic functions, pain pathways, auditory and vestibular functions.
- Cerebellum: Coordinates motor and sensory information; vital for balance and posture.
-
Brain Stem: Midbrain, pons, and medulla oblongata.
- Midbrain: Sensory and motor information relay station.
- Pons: Information relay station, breathing.
- Medulla Oblongata: Regulation of heart rate, blood pressure, breathing, coughing, sneezing, swallowing, and vomiting.
-
Diencephalon: Thalamus, hypothalamus, pineal body, and pituitary gland.
- Thalamus: Relays and processes information to cerebrum.
- Hypothalamus: Regulates hormones, temperature, H2O levels, thirst, emotions, and pituitary gland.
- Pineal Body: Body clock; produces melatonin.
- Pituitary Gland: Hormones.
-
Important Gyri to Know: Precentral and Postcentral Gyri.
- Precentral Gyrus: Primary motor cortex.
- Postcentral Gyrus: Primary sensory cortex.
- Important Brain Areas: Substantia Nigra (in basal ganglia, produces dopamine, role in movement), Broca's Area (nonfluent speech), Wernicke's Area (language comprehension deficits).
Important Brain Areas
- Substantia Nigra: Located in basal ganglia, produces dopamine (movement).
- Pineal Gland: Produces melatonin.
- Pituitary Gland: Hormones (endocrine function).
- Broca's Area: Nonfluent speech (frontal cortex).
- Wernicke's Area: Language comprehension deficits (temporal lobe).
Blood Supply
- Vertebral Artery: Supplies spinal cord and medulla.
- Basilar Artery: Supplies pons, cerebellum, midbrain, etc.
- Internal Carotid Artery: Supplies frontal and parietal lobes, lateral hemisphere.
CVA Presentations
- ACA: Personality changes, contralateral hemiplegia and hemisensory loss.
- MCA: Contralateral homonymous hemianopia, hemiplegia, hemisensory loss, language impairment.
- PCA: Neglect, thalamic syndrome possible, vision and eye issues.
Collateral Circulation
- Network to provide alternate pathways for blood flow.
Blood Brain Barrier
- Tightly joined epithelial cells control passage; only small, fat-soluble molecules naturally pass; active transport is necessary for water-soluble substances like glucose and amino acids.
Cerebral Spinal Fluid
- Regulates extracellular content and provides protection.
- Formed in the ventricles, circulates to the subarachnoid space, and is absorbed into venous circulation.
CSF: Ventricles and Layers
- Choroid Plexus: Secretes cerebrospinal fluid (CSF) within the ventricles.
- Meninges: Dura Mater, Arachnoid, Pia Mater.
Limbic System
- Involved in behavioral and emotional responses, including survival behaviours (feeding, reproduction, caring for young).
- Located in the thalamus, hypothalamus, basal ganglia, hippocampus, amygdala.
- Hippocampus: Memories.
- Amygdala: Emotional Response.
Corpus Callosum
- Connects right and left hemispheres.
- Left hemisphere typically associated with language; right hemisphere typically associated with attention, memory, reasoning, problem-solving.
