Chapter 2: Terms Pertaining to the Body as a Whole In this chapter you will 1. Define terms that apply to the structural organization of the body. 2. Identify the body cavities and recognize the organs contained within those cavities. 3. Locate and identify the anatomical and clinical divisions of the abdomen. In this chapter you will 4. Become acquainted with terms that describe positions, directions, and planes of the body. 4. Identify meanings for new word elements and use them to understand new medical terms. Structural Organization of the Body Major Parts of a Cell (p. 32) Types of Cells (p. 36) Muscle cell Nerve cell Epithelial cell Fat cell Tissues A group of similar cells working together to do a specific job – Epithelial tissue – all tissues that cover the outside of the body and line the inner surfaces of internal organs. – Muscle Tissue – Connective tissue – fat, cartilage, bone, blood. – Nerve tissue Organs Structures composed of several kinds of tissue – Heart – Stomach Viscera: internal organs Systems Groups of organs working together to perform complex functions – Cardiovascular System – Digestive System 1. Cranial Cavity – page 39 Brain Pituitary gland Cranial Cavity 2. Thoracic Cavity – page 39 Pleural Cavity – Lungs Mediastinum – Heart – Esophagus – Trachea – Bronchial tubes – Thymus gland – Aorta Thoracic Cavity Diaphragm separates the thoracic and abdominal cavities 3. Abdominal Cavity – page 39 Stomach Small and large intestines Spleen Pancreas Liver Gallbladder Abdominal Cavity 4. Pelvic Cavity – page 39 Portions of the small and large intestines Rectum Organs of the urinary system Organs of the reproductive system Pelvic Cavity 5. Spinal Cavity – page 39 Nerves of the spinal cord Spinal Cavity Dorsal (posterior) Cavities Cavities in the back of the body – Cranial – Spinal Ventral (anterior) Cavities Cavities in the front of the body – Thoracic – Abdominal – Pelvic Abdominopelvic Regions (p. 44) R&L Hypochondriac Epigastric R&L Lumbar Umbilical R&L Inguinal Hyopgastric Abdominopelvic Quadrants (p. 45) Right Upper – Gallbaldder – Liver Right lobe – Parts of Pancreas Small Intestines Large Intestines Abdominopelvic Quadrants (p. 45) Left Upper – Stomach – Liver Left lobe – Parts of Pancreas Small Intestines Large Intestines Abdominopelvic Quadrants (p. 45) Right Lower – R ovary – R fallopian tube – Appendix – R ureter – Parts of Small Intestine Large Intestine Abdominopelvic Quadrants (p. 45) Left Lower – L ovary – L fallopian tube – L ureter – Parts of Small Intestine Large Intestine Divisions of the back and spinal column (p. 46) Cervical (7) Thoracic (12) Lumbar (5) Sacral (5) Coccygeal (4) Positional and Directional Terms (p. 48) Planes of the Body (p. 48-49) Planes of the Body (p. 48-49) 1. Frontal (coronal) Plane Vertical plane Divides the body into – anterior – posterior Frontal (Coronal) Plane 2. Sagittal (lateral) Plane Vertical plane Divides the body or structure into – right side – left side Sagittal (Lateral) Plane 3. Transverse (cross-sectional) Plane Horizontal plane Divides the body or structure into – upper half – lower half Transverse (cross-sectional) Plane Chapter 2 Terms Pertaining to the Body as a Whole Pages 50-53 abdominal abdomin/o: abdomen -al Pertaining to the abdomen adipose adip/o: fat -ose: pertaining to Pertaining to fat anterior anter/o: front -ior: pertaining to Pertaining to the front anabolism ana-: up bol/o: to cast (throw) -ism: process Process of casting up – The building-up or synthesizing process in a cell. cervical cervic/o: neck -al Pertaining to the neck chondroma chondr/o: cartilage -oma Tumor of cartilage – Benign chondrosarcoma chondr/o Sarc/o: flesh -oma Flesh tumor of cartilage – Malignant chromosomes chrom/o: color -some: body Color bodies – They absorb the color of dyes used to stain the cell – Contain genetic material – Located in the nucleus coccygeal coccyg/o: coccyx -al Pertaining to the Coccyx (tailbone) craniotomy crani/o: skull -tomy Incision of the skull cytoplasm cyt/o -plasm: formation Formation (contents) of the cell distal dist/o: far, distant -al Pertaining to far – From the beginning of a structure dorsal dors/o: back -al Pertaining to the back histology hist/o: tissue -logy Study of tissues iliac ili/o: ilium -ac Pertaining to the ilium, part of the pelvic bone. inguinal inguin/o: groin -al Pertaining to the groin karyotype kary/o: nucleus -type: classification, picture Picture or classification of the nucleus – And its chromosomes lateral later/o: side -al Pertaining to the side lumbosacral lumb/o: lower back sacr/o: sacrum -al Pertaining to the lower back and sacrum medial medi/o: middle -al Pertaining to the middle nucleic nucle/o: nucleus -ic Pertaining to the nucleus pelvic pelv/o: hip, pelvic cavity -ic Pertaining to the hip or pelvic cavity posterior poster/o: back -ior Pertaining to the back proximal proxim/o: near -al Pertaining to near – A structure sacral sacr/o: sacrum -al Pertaining to the sacrum sarcoma sarc/o -oma Tumor of flesh – malignant spinal spin/o: spine -al Pertaining to the spine epithelial cell epi thel/o: nipple -al Pertaining to upon a nipple – Skin cell thoracic thorac/o: chest -ic Pertaining to the chest thoracotomy thorac/o -tomy Incision of the chest. tracheal trache/o: trachea -al Pertaining to the trachea umbilical umbilic/o: navel -al Pertaining to the navel ventral ventr/o: belly side of the body -al Pertaining to the belly side of the body vertebral vertebr/o: vertebrae -al Pertaining to vertebrae visceral viscer/o: internal organs -al Pertaining to internal organs anabolic ana bol/o -ic Pertaining to casting up – building up substances (proteins) in the cell catabolism cata-: down bol/o -ism Process of casting down – breaking down material in the cell to release energy – Mitichondria epigastric epi gastr/o -ic Pertaining to above the stomach hypochondriac regions hypo chondr/o -iac Pertaining to below (rib) cartilages intervertebral inter-: between vertebr/o -al Pertaining to between the vertebrae metabolism meta-: change bol/o -ism Process of casting change – Anabolism and catabolism
