Neural Tissue

4.On a neuron, the branch-like structures that receive messages from other neurons are the dendrites.

Describe the anatomy of the neuron and the ways that neurons communicate with each other.

4. You are shown a picture of an elephant. Explain how that stimulus is processed from the retina to the visual cortex of the brain.

Midterm Essay ExaminationMidterm Essay Examination1.Describe the basic functioning of a neuron beginning with receiving signals from other neurons or sense organs and ending with the transmission of a signal to another neuron. Explain how a pattern of neuron firing is related to behavior.

Purpose: What is the purpose of this exercise? Are there any safety concerns associated with this exercise? If so, list what they are and what precautions should be taken. To understand the structure and function of multipolar neuron,unipolar and bipolar neurons. Also to identify the structures of a nerve. There are no safety concerns for this lab.

1b. List and describe briefly the major structures of the brain, as presented in your textbook, including the function of those elements that are most related to psychoactive drug reaction.

The cell body comprises of the nucleus and other organelles (Ward, 2010). The nucleus contains the genetic code, and this is involved with protein synthesis (He, 2013). The dendrites receive information from other neurons which are located in a close proximity (Kalat, 1995). The terminal of an axon compresses into a disc-shaped structure (Gross, 2010). This is where chemical signals also known as a neurotransmitter permit interaction amongst neurons, by means of a minute gap named a synapse (Martin, Carlson & Buskit, 2013). Both neurons which form the synapse are referred to as a presynaptic synapse (prior to the synapse) and postsynaptic (after the synapse), reflecting the direction of information flow (from axon to dendrite), (He, 2013).

2-1: What are the characteristics of epithelial tissue? _Polarity, Specialized contacts, Supported of connective tissue, Avascular but innervated, Regeneration___

What are the two divisions of the ANS? Where are the neurons for each division located, and what is the major function of each division?

1. Describe the basic functioning of a neuron beginning with receiving signals from other neurons or sense organs and ending with the transmission of a signal to another neuron. Explain how a pattern of neuron firing is related to behavior.

1. (6pts) Diagram a neuron and label its components. In what ways are neurons specialized for communication? How do these specializations distinguish neurons from other types of cells?

In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue.

In the article, “Stem-Cell Research Utilizing Embryonic Tissue Should Not Be Conducted”, Bertha Alvarez Manninen argues on the basis that it is unethical to allow the destruction of embryos in order to further stem-cell research, by relating it to the destruction of human life. Manninen explains the different stages of the human embryo and how it can be legally justified as a human. Therefore, an embryo can be defended by basic human rights. She supports this using Kant’s formula of humanity, which, in summary indicates that humanity should never be treated as a means to an end.

We have known the amazing benefits of human tissue in medical research. These cells have helped with some of the most important advances in the sciences. They are used to develop vaccines for rabies, smallpox, and measles or used for radiation, drugs, cosmetics and viruses research which launched a million dollar industry [ Skloot, 316]. They have been used to find the cure for multibillion people, including most of us today. However, not that many people know where are these tissues come from or the stories of the “donors” who were desperate to protect their bodily rights and property rights. Most of the patients in the late 1950s have not been asked if they want to contribute their tissues to science, which has raised the debate over

The human brain is made up of soft tissue, cushioned by spinal fluid and encased in the protective shell of the skull. Keeping the brain structure in mind, a concussion is commonly caused by a sudden direct blow or a bump to the head. This causes the brain to jolt inside the skull, further leading to the state of confusion most people wake to. Some may even lose consciousness, or even sustain permanent brain or nerve damage. Since concussions are internal, the behavior of the person must be challenged and questioned in order to determine whether or not they sustained a concussion.
