EATING SPAGHETTI! Leanna Stafford
Sensory Neurons are involved in EATING SPAGHETTI • The smell of food is apart of external conscious. This action is controlled by sensory neurons. NOT Motor neurons. Sensory neurons are involuntary. The action of smelling food is uncontrollable.
Neurons Active Role in Eating Spaghetti Neurons cannot store glucose. So, they are dependent on the blood stream to deliver a constant supply of precious fuels. Carbohydrates are broken down into glucose by cellular respiration into ATP (Energy). Neurons demand a lot of energy because they’re always in a state of metabolic activity. Neurons are manufacturing enzymes and neurotransmitters that are transported out to very ends of their nerve-branches. Chemo receptors is a sensory receptor that is involved in smell and/or taste. They convert a chemical signal into an action potential. Knowing the taste of spaghetti is controlled by direct chemo receptors. The smell of spaghetti is controlled by distant chemo receptors. The resulting output from the brain, the Central Nervous System will make the body indulge the food. This relates back to means of survival.

Travel of Neuron Impulses The gap between two neurons is called a synapse. The blue bubbles in the diagram contain chemicals that pour out in the axon terminal of one neuron, cross the synapse, and trigger a nerve impulse in the second neuron. The electrical signal is changing from positive to negative, and it moves the nerve impulse along a neuron. Neurons are in a fiber-like bundle called a nerve, and the impulses are all traveling in the same direction.
Gastrointestinal Physiology • Autonomic Nervous System • Apart of the peripheral nervous system. This system is divided into two parts. Sympathetic Nervous System and Parasympathetic Nervous System. The Parasympathetic Nervous System controls digestion and absorption of nutrients. • http://en.wikipedia.org/wiki/Autonomic_nervous_system • Stimulation Modified smooth muscle cells called interstitial cells of Cajal cause spontaneous cycles of slow wave potentials that can cause action potentials in smooth muscle cells. Ca channels smooth muscles open. Ions being secreted during this process include: H, K, Cl, HCO3, Na.
Neurotransmitters Given off From the Consumption of Spaghetti and Meat Balls • Dopamine: A hormone & neurotransmitter that plays an important role in cognition, behavior, learning, motor functions, sleep, attention span, & mood. • Serotonin • Monoamine neurotransmitter that is synthesized in neurons of central nervous system & in cells in intestinal walls. This modulates anger, mood, sleep, sexuality, and appetite. • Increases with the consumption of carbohydrates (pasta). • http://www.faqs.org/nutrition/Met-Obe/Mood-Food-Relationships.html • Nor epinephrine • Catecholamine, chemical compounds derived from the amino acid, tyrosine. Secreted by adrenal medulla. This neurotransmitter/hormone affects physical & emotional responses to stress. Increases with the consumption of meat. Proteins are broken down by the body into amino acids like L-Tyrosine.
