What is primary tissue culture? Several different types of culture are routinely performed. The Classification of tissue cultures is based on the origin of the cells; which can roughly be divided into "primary culture" and "culture of established cell lines." Primary tissue culture can consist of the culture of a complex organ or tissue slice‚ a defined mixture of cells‚ or highly purified cells isolated directly from the organism. Compared to a cell line using primary culture has the advantages

Introduction: In this lab‚ I will study how muscles contract‚ what makes muscles contract‚ different types of muscle contraction‚ and learn about how resistance affects muscle contraction. I will define Key Terms that describe what will occur in the experiments; I will conduct an experiment for each Activity and provide all resulting Data as well as answer Questions from each Activity. I will then provide a short Summary for what I learned in each Activity. Key Terms: Recruitment (or Multiple

Anatomy and Histology of the Small and Large Intestine MACROSCOPIC FEATURES Small Intestine The small intestine is a specialized tubular structure within the abdominal cavity in continuity with the stomach proximally and the colon distally. The small bowel increases 20 times in length with aging‚ from 200 cm in the newborn to almost 6 m in the adult‚ and its length is approximated by three times the length of the infant‚ or height of the child or adult.[1] The duodenum‚ the most proximal

fiber-like cells that ties the axons of each fascicle together. Epineurium is the connective tissue that surrounds the entire nerve trunk and gives off vascular connective tissue septa that traverse the nerve and separate fascicles from one another. | | Single myelinated axon | Normal nerve | Axons thicker than one micron in the CNS and peripheral nervous system (PNS) are myelinated. Myelin is a spiral sheet of cell membrane wrapped around the axon. In the CNS‚ myelin is produced by oligodendroglial

Activity 1 1. Size and concentration of the solute 2. It was too large to pass‚ as predicted 3. I predicted that the glucose would diffuse since it is small enough but the albumin is much too large to pass through the membrane. The experiment produced this result. Activity 2 1. Neither way requires ATP but facilitated diffusion requires carrier protein molecules for diffusion to occur. 2. By increasing the number of carriers more glucose can pass at a time increasing the rate‚

Compare and Contrast Sommia Khan Dr. Doumen Exocrine versus Endocrine glands: The similarities between exocrine and endocrine glands are that they are both glandular tissues. Glandular tissues are generally composed of cuboidal cell or columnar cell. Exocrine glands release substances like sweat and saliva through ducts on to the surface of the body. Exocrine glands include merocrine sweat glands‚ apocrine sweat glands and holocrine glands. Merocrine sweat glands‚ also known as eccrine sweat glands

The Theme of "Meditation 17" Armed with the use of metaphor and paradox‚ John Donne brilliantly develops the theme of "Meditation 17." He proclaims that we are all a part of the whole in which everyone’s actions affect one another. Someone’s death‚ compared to the tolling of the bell‚ indirectly affects one even though "that he knows not it tolls for him." The ringing of the bell reminds one of death and how close it is. There are no atheists at life’s end. We are born dying‚ and as we realize
