▪ Blood is supplied from splenic artery, gastroduodenal artery, & superior mesenteric artery. • Roles of Pancreas o Assists in digestion of foods by secreting enzymes, especially fats & proteins. o Precursors of enzymes (zymogens), converted to amylase & pancreatic lipase. o Secretes sodium bicarbonate to neutral stomach acid. o Exocrine functions of pancreas are controlled by hormones secreted by the stomach & duodenum. o Exocrine secretions of pancreas flow into pancreatic duct & are delivered to duodenum through pancreatic duct. Nervous System o Human nervous system senses, interprets, & issues commands o Action potential: messages sent across the plasma membrane of neurons. ▪ Messages occur when a neuron is stimulated past a necessary threshold. ▪ Stimulations occur in a sequence from one stimulation point of one neuron to its contact with another neuron. ▪ Chemical synapse: A substance released that inhibits the action of the adjoining cell. o Functional Types of Neurons ▪ Three general function of neurons are • sensory neurons, motor neurons, and interneurons. • Sensory neurons: Transmit signals to the central nervous system (CNS) from the sensor receptors associated with touch, pain, temperature, hearing, sight, smell, & taste.
