With new technologies such as cell cultures‚ human tissues‚ and in vitro tests‚ we are able to replace some of the tests that cause harm and discomfort to those animals. According to Cruelty Free International‚ cell cultures‚ also known as

They are comprised of compact connective tissue consisting of collagen fibers. The peritenon is a layer of loose connective tissue that wraps around the tendon. Large tendons have lymphatics and vessels that course between septa‚ and small tendons have almost no vascularity. Tendons can attach to tuberosities‚ processes‚ or ridges. Synovial

They serve as selective barriers‚ transport functions‚ or movement of mucus and detritus over surfaces. Some epithelial tissues serve sensory functions as well. B) Connective tissues are dispersed populations of cells embedded in an extracellular matrix that the cells themselves secrete

TMA 2 Part 1 Describe how neurons in the central nervous system communicate. Using examples‚ discuss how this has helped us to understand human behaviour. Human cognition‚ emotion‚ motivation and ultimately life is made possible by neurons in the central nervous system (CNS). This essay will briefly describe the processes involved in neuronal communication and discuss how this knowledge has helped improve our understanding of human behaviour‚ specifically with regards to neurological

Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists of
