1. There are 3 types of neurons. Motor, sensory, and Interneurons. The main parts of the neuron are dendrites, the soma, the axon, the axon terminal, the synapse, and the myelin sheath. The dendrites are branch like bushy extensions that receive the information and conduct impulses towards the cell body. The soma, or cell body, makes sense of the information and works It out. It also triggers the action potential and all or nothing response. The axon is a neuron’s extension that sends messages to other neurons or to muscles or glands. It transmits the Impulse, aka the action potential. The axon terminal, or the terminal button is the end of the axon and it houses the synaptic vesicles, synaptic vesicles, and neurotransmitters which are the …show more content…
The main three sections of the brain are the hindbrain, the limbic system, and the cerebral cortex. The hindbrain consists of the medulla which is directly above the spinal cord and controls breathing, heartbeat, and other vital life functions like the things we don’t have conscious control over. It also has pons which are in the uppermost level of the hindbrain and just above the medulla, they serve as a bridge and information from higher parts of the brain revels through these to get to the cerebellum which is behind the pons, at the back of the brain stem also known as “little brain” this coordinates movement, balance, and posture. The last thing the hindbrain has in the reticular formation which is located at the core of the medulla and pons. They are groups of specialized neuron that project up to higher brain regions and down the spinal cord and regulate alert and attention. The limbic system contains the hippocampus, thalamus, hypothalamus, and amygdala. The hippocampus is located in the temporal lobes on each side and is involved with making memories, neurogenisis takes place here. The thalamus is a mass of cell bodies located within each cerebral hemisphere and processes and interegates sensory informations except for smell and relays sensory information to cerebral cortex. They’re like traffic cops. The hypothalamus is located right below the thalamus and is the size of a peanut. It links the brain to the endocrine system and regulates the four f’s that are …show more content…
The major lobes are the frontal, parietal, occipital, and temporal. The frontal is located in the front of the brain and affects your consciousness, decisions, personality, and ability to answer questions. It is involved in speaking, making plans, and judgment and contains Broca’s area which is what allows you to be able to speak. In the back of the frontal lobe you’ll find the motor cortex which controls voluntary movement. Next , in the front of the parietal lobe you’ll find the sensory cortex that registers and processed body touch and movement sensations. This is located in the parietal lobe which is from the top of the head to the rear and receives sensory input for touch and body position. The occipital lobe is in the back of the head and receives information from the visual fields. And lastly, theres the temporal lobes located just above your ears. It processes sounds and speech, and may be involved with long term memory. This contains Wernicke’s area that allows you to process
