Lecture 1 12017 There are 11 systems of organs that work together: Integument (skin) protects the body from damage Skeletal system support, protection of soft tissues; mineral storage; blood formation Muscular system locomotion, support, heat production Nervous System directing immediate responses to stimuli, usually by coordinating the activities of other organ systems Endocrine System directing long term changes in the activities of other organ systems Cardiovascular System internal transport of cells and dissolved materials, including nutrients, wastes, gases Lymphatic system Immune system defense against infection and disease Respiratory System delivery of air to sites where gas exchange can occur between the air and circulating blood Digestive System processing of food and absorption of organic nutrients, minerals, vitamins, and water Urinary System elimination of excess water, salts, and waste products; control of pH Reproductive System production of sex cells and hormones Anatomical Language: Anatomical Position Standing up position, Front eyes palms forward, Thumbs away from body. No two bones crossing Sagittal plane extends vertically and divides the body or organ into right and left sections o Median (midsagittal) plane passes through the midline of the body and divides it into equal halves o Parasagittal planes divide the body into unequal right and left positions Frontal (coronal) plane extends vertically, and is perpendicular to the sagittal plane and divides the body into anterior and posterior planes. (corona crown) Transverse (horizontal) plane passes across the body or an organ perpendicular to its long axis. Divides the body into superior and inferior portions Directions: Posterior Back of the body Anterior front of the body Superior closer to the head Inferior away from the head Medial Closer to midline Lateral away from midline Proximal closer to the point of attachment or origin Distal further from the point of attachment or origin Superficial closer to the body surface Deep further from the body surface Ipsilateral same side of the body Contralateral opposite sides of the body
