Brian Dissection Lab



2. Anterior Side: The frontal section of the brain.
Posterior Side: The back of the brain closest to the back of the head. 
Cerebrum: The largest part of the human brain, associated with higher brain function such as thought and action. The cerebrum is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe
Cerebellum: it contributes to coordination, precision, and accurate timing. It receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity.
Brain Stem: controls the flow of messages between the brain and the rest of the body, and it also controls basic body functions such as breathing, heart rate, blood pressure, consciousness, and whether one is awake or sleepy. The brain stem consists of the midbrain, pons, and medulla oblongata.


3. Function of the Myelin Neuron is it protects and insulates the fibers and increases the transmission of an impulse.

5.

Hypothalamus: Maintains homeostasis for body temperature. 
Optic Nerve: Allows the brain to "see"
Corpus Callosum: Connects the right and left hemispheres 
Thalamus: Sorts data in the brain such as its ability to comprehend what it is seeing, what it is hearing, what it is touching and it also regulates sleep and wakefulness. 
Mid Brain: Is a part of the brian (in the middle part of the brain) that is associated  with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.
Pons: The pons is located in the upper part of the brain stem and is associated with the control of breathing, communication between different parts of the brain, and  hearing, taste, and balance.
Medulla Oblongata: This part of the brain helps regulate a bunch of things such as breathing, heart function, digestion, and sneezing. This is where the brain controls respiration and circulation too.
