Anatomy and Physiology The Language of Anatomy MCON 01 (LABORATORY) | BSN 1-4 Directional Terms – describe one body LESSON I: Orientation and Introduction of structures in relation to another body structures the Human Body and the direction is always based on standard anatomical position A. DIRECTIONAL TERMS Superior (cranial or cephalic) – towards the head end or upper part Homeostasis of a structure of the body; above - Balance / state of balance among Ex. The head is superior to the neck all the body systems needed for the body to survive and function Inferior (caudal) – away from the correctly head end or towards the lower part of structure of the body; below 1. Stimulus – factors coming from the Ex. The abdomen is inferior to the thorax. environment that causes changes in the human body, such as increase or decrease in temperature or presence of a Anterior (ventral) - at the front of the body; in front of pathogen Ex. The sternum is anterior to the heart. 2. Receptor – type of sensory that monitors and responds to changes in the environment (stimuli) by sending Posterior (dorsal) –at the backside of information (input) to the second the body; behind components Ex. The spinal cord is posterior to the heart. 3. Control Center – this component analyzes the information it receives from the receptor and then determines the Medial – midline of the body: on the appropriate response or course of action inner side of 4. Effector – it provides the means for the Ex. The nose is medial to the eyes. control center’s response (output) to the stimulus Lateral - away from the midline of the 5. Response – corrective measure of the body: on the outer side of body to the stimulus in the body. Can Ex. The ears are lateral to the nose. either be positive or negative feedback mechanism Intermediate – between a more medial and more lateral structure Ex. The collarbone is intermediate between the sternum and the shoulder. Proximal – close to the origin of the body part or the point of attachment of a limb to the trunk Ex. The elbow is proximal to the wrist. (Ina-add ko ‘to dito kasi baka kasama siya bigla, better na Distal – farther from the origin of the aralin na rin huhu) (homeostasis) body part or the point of attachment of a limb of the body trunk Ex.

As explained Translation - the language of C.

Fibrous (structural) proteins are the - Translation occurs in the cytoplasm major building materials for cells. Other and involves three major varieties of proteins, the globular (functional) proteins, RNA. perform functional roles in the body. - It follows, then, that every cell needs to produce proteins, a process called protein synthesis. Protein synthesis involves two major phases: transcription, when complementary mRNA (the messenger) is made using the information in the DNA gene, and translation, when the information carried in mRNA molecules is “decoded” and translated from nucleic acids into proteins. Transcription D. EPITHELIAL TISSUE - involves the transfer of information - or epithelium is the lining, covering, and from the sequence of bases in a DNA glandular tissue of the body. Covering gene into the complementary and lining epithelium covers all free body sequence of mRNA by an enzyme. surfaces, both inside and out, and contains versatile cells. Because epithelium forms the boundaries that separate us from the outside world, nearly all substances that the body gives off or receives must pass through epithelium. SIMPLE EPITHELIA 1. Simple Squamous Epithelium – single layer of thin squamous cells resting on a SIMPLE CUBOIDAL EPITHELIUM basement membrane. - usually forms membranes where filtration or exchange of substances by rapid diffusion occurs. 2. Simple Cuboidal Epithelium - one layer of cuboidal cells resting on a basement membrane, and is common in glands and their ducts - also forms the walls of the kidney tubules and covers the surface of the ovaries 3. Simple Columnar - made up of a single layer of tall cells that fit closely together - often seen with Goblet cells, which produce a SIMPLE COLUMNAR lubricating mucus 4. Pseudostratified Columnar - some of its cells are shorter than others, and their nuclei appear at different heights above the basement membrane, giving off a false (pseudo) impression that it is stratified PSEUDOSTRATIFIED COLUMNAR SIMPLE SQUAMOUS STRATIFIED EPITHELIA 1. Stratified Squamous - the most common STRATIFIED SQUAMOUS stratified epithelium in the body - the cells at the free edge are squamous cells, whereas those close to the STRATIFIED CUBOIDAL AND basement membranes are cuboidal or COLUMNAR columnar - found in sites that receive a good deal 2. Stratified Cuboidal and Columnar - Stratified cuboidal typically has just two cell layers with the cuboidal surface cells - stratified columnar’s surfaces are columnar cells, but its basal cells vary in size and shape 3. Transitional Epithelium - -highly modified, stratified squamous epithelium that forms the lining of only a few organs TRANSITIONAL EPITHELIUM (urinary) - basal layer cells are cuboidal or columnar; free surface vary in appearance 4. Glandular Epithelium - Endocrine glands lose their ducts, and their secretions (all hormones) diffuse directly into the blood vessels that weave GLANDULAR EPITHELIUM through the glands - Exocrine glands retain their ducts, and their secretions exit through the ducts to the epithelial surface. E. CONNECTIVE TISSUE - It perform many functions, but they are primarily involved in protecting, supporting, and binding together other body tissues. STRATIFIED SQUAMOUS TYPES OF CONNECTIVE TISSUE Bone - sometimes called osseous tissue, is composed of osteocytes (bone cells) sitting in cavities called lacunae (“pits”). - These pits are surrounded by layers of a very hard matrix that contains calcium salts in CARTILAGE addition to large numbers of collagen fibers. Cartilage -is less hard and more flexible than bone. Its major cell type is chondrocytes (cartilage cells). -Most widespread is hyaline cartilage, which has abundant collagen fibers hidden by a rubbery matrix with a glassy, blue-white appearance. It forms the trachea, or windpipe, attaches the ribs to the breastbone, and covers bone ends at joints. - Elastic cartilage is found in structures with elasticity, such as the external ear. DENSE CONNECTIVE TISSUE Dense Connective Tissue - also called dense fibrous tissue, collagen fibers are the main matrix element. - Crowded between the collagen fibers are rows Loose Connective Tissue of fibroblasts (fiber-forming cells) that manufacture the building blocks of the fibers. -tissues are softer and have more cells and fewer fibers than any other connective tissue type except blood. There are three main types of loose connective tissue: areolar, adipose, and reticular. BONE 1. Areolar Connective Tissue - the most widely distributed connective tissue variety in the body, is a soft, pliable, “cobwebby” tissue that cushions and protects the body organs it wraps. 2. Adipose Connective Tissue RETICULAR CONNECTIVE TISSUE - is commonly called fat. Basically, it is an areolar tissue in which adipose (fat) cells predominate. 3. Reticular Connective Tissue - consists of a delicate network of interwoven reticular fibers associated with reticular cells, which resemble fibroblasts. BLOOD AREOLAR CONNECTIVE TISSUE F. MUSCLE TISSUE - are highly specialized to contract, or shorten, which generates the force required to produce movement. There are three types of muscle tissue: skeletal, cardiac, and smooth. - Skeletal muscle - is packaged by connective tissue sheets into organs called skeletal muscles, which are attached to the skeleton. - Smooth Muscle - Smooth (visceral) muscle is so called because no striations are visible. ADIPOSE CONNECTIVE TISSUE - Cardiac muscle is found only in the heart wall. G. NERVOUS TISSUE - When we think of nervous tissue, we think of cells called neurons. All neurons receive and conduct electrochemical impulses from one part of the body to another; thus, irritability and SKELETAL MUSCLE conductivity are their two major functional characteristics.
