Lab IX: Nervous System Histology and Spinal Cord Part II: Neurons and nerve struture 1.) There are three types of neurons. The first is the multipolar‚ which is the most common‚ and they are found as motor neurons and interneurons throughout the central nervous system. The second type of neuron is the unipolar neuron‚ which are also called psuedounipolar neurons. They are found as spinal and cranial sensory neurons. The last neuron is the bipolar neuron. They are only found in olfactory‚ visual

Kathleen thomason October 2‚ 2012 Skeletal Muscle physiology exercise Electrical Stimulation name each phase of a typical muscle twitch and on the following line. Describe what is happening in each phase. a) latent- is a short period between the time of stimulation and the beginning of contraction b). Contraction – at this stage the muscle reaches its peak in contraction. Relaxation -Muscle is shortened‚ returns to zero and back initial length.

ANIMAL HISTOLOGY LAB REPORT OBJECTIVES • To identify the structure of various types of animal tissues • To explain the organization of the tissues HYPOTHESIS • Various type of tissues can be identified their function by observing the shape and structure of the cells because different tissues have different functions. • The usage of higher magnification of objective lens produces a better image. INTRODUCTION Internal structure of animal is made up cells. Cells aggregate and forms tissue. Animal

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the

There are four types of tissue found in animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin

There are three different types of epithelial tissues that are found inside the human body. There is the cutaneous membrane (tissue)‚ which we would refer to as “skin”. This part is the only epithelial tissue that is touched by air and is dry. The cutaneous membrane is composed of keratinizing stratified squamous epithelium. The second is the mucous membrane‚ which is the tissue used for absorption and secretion‚ protective lubricating mucus in the repertory and digestive system. This membrane
