BCS 145 LAB: AXIAL SKELETON WHY ARE WE DOING THIS LAB? The skeletal framework of the body is composed of at least 206 bones and the associated tendons‚ ligaments‚ and cartilages. The skeletal system has a variety of important functions‚ including‚ the support of soft tissues‚ blood cell production‚ mineral/electrolyte and lipid storage‚ and‚ through its relationships with the muscular system‚ the support and movement of the body as a whole. Skeletal system disorders can thus affect many other

Framework of the Skull The bony framework of the head‚ called the skull‚ is subdivided into two parts: the cranium and the facial portion. Refer to Figures 3-5 through 3-8‚ which show different views of the skull‚ as you study the following descriptions. Color-coding of the bones will aid in identification as the skull is seen from different positions. Cranium This rounded chamber that encloses the brain is composed of eight distinct cranial bones. * The frontal bone forms the forehead‚ the anterior

Introduction: The purpose of this experiment is to use sodium borohydride to reduce benzil. However‚ stereochemistry allows for five possible products. If only one carbonyl group is reduced during the reaction a racemic mixture of benzoin will be the product that is produced. After the first reduction a chiral center forms causing the second reduction to occur from only one side of the ketone. Depending on which side the second reduction take place there are three possible products including: a racemic

Subject: Thin-Layer Chromatographic Analysis of Drug Components (Experiment #15) The purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane. I noticed that my unknown was a coated tablet.

filtration is a non-adsorptive chromatography technique that separates molecules on the basis of molecular size. Desalting and buffer exchange are two special examples of gel filtration that are widely used in many downstream bioprocesses. Desalting is used to completely remove or lower the concentration of salt or other low molecular weight components in the sample while buffer exchange replaces the sample buffer with a new buffer. Gel filtration is one of the easiest chromatography methods to perform because

Neck pain Neck pain can be caused by many conditions. Here I mainly talk about nonspecific neck pain. Nonspecific neck pain is the most common type of neck pain. Acute neck pain is a sudden-onset pain in the neck. It is often due to neck muscle strains‚ muscle spasm or tendon or ligament sprain. This can be caused by poor posture‚ sleep in an awkward position‚ carrying heavy loads‚ stay in one position for a prolonged period of time for example‚ working on desk‚ or driving for long period of time

usually masked by the prevalence of the green chlorophyll. Anothocyanin(red or purple)‚ carotene(orange)‚ and xanthrophyll(yellow) are found in different proportions in different leaves. Leaf pigments can be separated by using paper chromatography. Paper chromatography is a technique that extracts pigments into a paper filter called chromatogram. What are the pigments are in Red Wondering Jews? Carotenoids These pigments primarily absorb in the blue wavelengths‚ allowing the longer wavelengths

Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly
