CH. 1 ANATOMY Introduction Anatomy: the study of structure Not physiology, which is functional There are 2 levels: 1. Microscopic Can’t be seen by naked eyes Cytology: cellular anatomy Histology: tissues 2. Gross Macroscopic Can be seen by naked eye Anatomy and Disease Pathologic: anatomic changes from disease Radiographic: ultrasound, MRI, X-ray to study relationships between internal structures Surgical: anatomic landmarks before and after surgery Structural organization of the body CHEMICAL CELLULAR TISSUE ORGAN ORGAN SYSTEM ORGANISMAL Example: Atoms Cell Epithelial Tissue Lung Respiratory System Human Living things: Try using GR ROAR M. I know its silly, but just think, “GRRR ROAR, EM!” This spells the 7 characteristics of living things: Growth and development: the increase of size and function Responsiveness: Responding to internal and external environment Regulation: HOMOSTASIS consistent internal environment Organization: Order to the complex structures Adaptation: Altering oneself to gain long-term success Reproduction: Produce new cells for growth, maintenance, repair, reproduce Metabolism: Chemical reactions that breakdown ingested food, use cells energy to perform function, or contract/relax muscles to move body. Organ Systems Integumentary Skin, hair, glands Skeletal Bones, cartilage Muscular Muscles Nervous Central/ peripheral nervous system Endocrine Glands, hormones Cardiovascular Heart, blood, blood vessels Lymphatic Lymph nodes Respiratory Nose, throat, lungs Digestive Mouth, liver, stomach, intestines Urinary Kidney, bladder Reproductive Male, female Anatomic Position: Feet on Floor Head level Eyes forward Arms at side Palms forward Thumbs pointing out Planes and Directions: Coronal: anterior/ posterior (front/ back) Transverse: superior/ interior (upper/lower) Midsagittal: equal right and left halves End of actual page content Directional Terms: Anterior/ Posterior: Front/ Back / Dorsal/ Ventral: Backside/ Bellyside (primarily spinal cord reference) Superior/ Inferior: Closer to head/ Closer to feet / Caudal: at rear or tail end (like an animal) Rostral: toward the nose (like an animal) Cranial: at the head end Medial/ Lateral: Toward midline/ Away from midline | / | Deep/ Superficial: inside/ outside (**) / *( )* Proximal/ Distal: closest to the point of attachment to the trunk/ furthest from the point of attachment from the trunk (attachment of limbs to body) Regional Anatomy Two main regions 1. Axial region: Head, trunk, neck 2. Appendicular region: Limbs Body cavities and membranes Pariet Cranial cavity: houses brain Serous Vertebral canal: contains spinal cord FlViscer Ventral cavity: diaphragm splits into Hear thoracic cavity abdominopelvic cavity t They are both lined with serous membranes Parietal: lines internal surface of body wall Visceral: lines external surface of the organ Serous fluid: located between membranes inside cavities Thoracic cavity Mediastinum: the thoracic cavity’s median space that contains the heart The heart is furthered enclosed by the membrane pericardium Thoracic cavity also contains the lungs The serous membrane lining the lungs is called pleura Abdominopelvic cavity Separated by an imaginary line drawn across hip bones Abdominal cavity: (superior) contains digestive organs, kidneys, ureters Pelvic cavity: (inferior) contains large intestine, bladder, urethra, reproductive organs The serous membrane is Peritoneum
