- Visit this site (http://openstaxcollege.org/l/nervetissue3) to learn about how nervous tissue is composed of neurons and glial cells. Neurons are dynamic cells with the ability to make a vast number of connections, to respond incredibly quickly to stimuli, and to initiate movements on the basis of those stimuli. They are the focus of intense research because failures in physiology can lead to devastating illnesses. Why are neurons only found in animals? Based on what this article says about neuron function, why wouldn't they be helpful for plants or microorganisms?Central nervous system (CNS) and peripheral nervous system (PNS) are two systems innervous system that control human movement and activity.(a) Describe the pathway of receiving and transferring information in neuron.Use logic to determine whether each of the following reflexes is a somatic reflex or an autonomic (visceral) reflex. Hint: think about what the effector is — is it a skeletal muscle, or is it a smooth / cardiac muscle or gland? -Patellar (knee-jerk) reflex -Pupillary light reflex (autonomic/somatic) -Effectors are skeletal muscles (autonomic/somatic) -Effectors are smooth muscles or glands (autonomic/somatic) -Regulation of blood pressure (autonomic/somatic) -Salivary reflex (autonomic/somatic)
- What is (are) the reason(s) behind the earliest development of the nervous system among all organ systems?What is the smallest structural and functional unit of nervous system?Visit this site (http://openstaxcollege.org/l/neurolab)to see a virtual neurophysiology lab, and to observeelectrophysiological processes in the nervous system,where scientists directly measure the electrical signalsproduced by neurons. Often, the action potentials occur sorapidly that watching a screen to see them occur is nothelpful. A speaker is powered by the signals recorded froma neuron and it “pops” each time the neuron fires an actionpotential. These action potentials are firing so fast that itsounds like static on the radio. Electrophysiologists canrecognize the patterns within that static to understand whatis happening. Why is the leech model used for measuringthe electrical activity of neurons instead of using humans?
- Name and briefly explain the three main functions of nervous system.What is affected by the electrical signal sent by the third structure? (This will be the fourth structure in the arc.) Where is the cell body of the fourth structure located? What is affected by the electrical signal sent by the fourth structure? (This will be the fifth structure in the arc.) What does the fifth structure do in response to that electrical signal and how does this action protect you? Describe a situation where a reflex arc would be activated that is not described in your lesson. Assume that the reflex arc has five components to it. Please choose a reflex that involves a body part below the neck. (If you have trouble with this, do an internet search for information on reflex arcs.)Which of the following is NOT true of the nervous system?(a) Consists of central and peripheral systems(b) Central nervous system is composed of brain and spinalcord(c) Ganglia are part of brain(d) Meninges are membranes that cover brain and spinalcord(e) Normally free of microbes
- Your nervous system is organized into two broad anatomical divisions: the central nervous system (consisting of the brain and spinal cord) and the peripheral nervous system (PNS). Your PNS is further organized into two functional divisions. If you tap your knee, the signal to act is carried via your to the muscles in your knee. In contrast, the signals that pass via the are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your that is primarily in action. The third division is your which helps control the components of the digestive system.What adaptive advantage do synapses provide in nervoussystems (i.e., why isn’t the nervous system just a mesh of cellscytoplasmically connected through gap junctions)?1.)
