Brain Dissection Assignment
Transcript of Brain Dissection Assignment
Occipital Parietal Frontal Temporal Dura Mater Pia Mater Brain Stem Medulla Oblongata Pons Central Sulcus Corpus Callosum Sulci Gyri Longitudinal Cerebral Fissure Post and Pre
Central Gyrus Diencephalon Hypothalamus Internal Cerebrum Midbrain Thalamus White and
Grey Matter Pineal Gland Internal
Cerebellum Most posterior aspect of cerebrum, separated by longitudinal cerebral fissure
Includes primary visual cortex- uses past stimuli to interpret current situation Small cauliflower like blob that’s 11% of total brain mass
Dorsal to Pons and medulla and protrudes under occipital lobes
Processes info from cerebral motor cortex
Subconscious usage- balance, posture, coordination Most inferior portion of brain stem
Cardio center- force and rate of heart contraction
Respiratory center- rate and depth of breathing
Other- vomiting, hiccupping, sneezing
Did you know? It contains decussation of the pyramids- responsible for why left side of the brain controls right side of body and vice versa Bulging area between midbrain and medulla oblongata
Pons= bridge therefore tracts in 2 directions motor cortex and cerebellum (voluntary and involuntary)
3 functions: attachment for cranial nerves, reticular formation and aide’s medulla in breathing rhythm Located between diencephalon and Pons
Controls “fight or flight response”
Visual reflex center-eye movement
In charge of auditory relay
Contains red nucleus- affects limb flexion
Hypo=below, below the thalamus
Includes mammilary bodies=relay station for olfactory system
Important for overall homeostatic balance: 1 ANS 2 emotional response 3 regulate body temp. 4 food intake 5 H20 balance & thirst 6 sleep-wake cycle 7 endocrine system
80% of Diencephalon (Hypothalamus is other 20%)
All afferent impulses synapse with at least one of its nuclei
Information is sorted here- “pleasant” versus “unpleasant”
Key role in: learning, memory and motor activities
Deep within longitudinal fissures (directly below parietal lobes)
Considered to be part of white matter
Did you know? It’s responsible for dividing the 2 hemispheres. Women’s are closer= ability to multitask, Men’s further apart= not able
Responsible for communication between cerebral areas and between cerebral cortex are & CNS Centers
Consists of myleinated fibers
Classified by direction they run as: commissural, association, projection White Matter Grey Matter Internal Brain Forms central core of the fore brain & is surrounded by cerebral hemispheres.
Consists of: Thalamus, Hypothalamus, Epithalamus.
Emotional response and memory processing. Cortical grey matter
Interprets sensory inputs, voluntary, muscle activity, intellectual and emotional processing. "Tough Mother"
Outermost and toughest of the three membranes covering the brain and spinal cord. A hormone-secreting art of the diecephalon of the brain thought to be involved in setting the biological clock and influencing reproductive function. Cortical grey matter
Interprets sensory inputs, voluntary, muscle activity, intellectual and emotional processing. Consists of the Midbraidn, pons, and medulla oblongata
Maintains cerebral cortical alertness
Filers out repetitive stimuli
Helps regulate skeletal and visceral muscle activity Elevated ridges of tissue
Mark the entire surface of the cerebral hemispheres Shallow grooves in brain tissue
Separate gyri Pre-Central Anterior to central sulcus. Posterior to central sulcus. Post-Central Separates the cerebral hemispheres from the cerebellum Separates the frontal lobe from the parietal lobe. Major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries. Cortical grey matter
Interprets sensory inputs, voluntary, muscle activity, intellectual and emotional processing. "Tender Mother"
Delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. The temporal lobe is involved in auditory perception and is home to the primary auditory cortex.
It is also important for the processing of semantics in both speech and vision.
The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory. Located on the lateral surface of the brain.
Contains most of the dopamine-sensitive neurons in the cerebral cortex. The dopamine system is associated with reward, attention, long-term memory, planning, and drive. Integrates sensory information from different modalities, particularly determining spatial sense and navigation.
Positioned superior to the occipital lobe and posterior to the frontal lobe. Anatomy of a Sheep Brain By: Angela Christopher, Kelsey Girbino and Jessica Wilgus White! Grey! The End!
