Study Guide
Question | Answer |
---|---|
Anatomy | Study of Internal and External Stuctures and their relationship |
4 Anatomy's | Gross, Regional, Systemic, Microscopic |
Gross Anatomy | Study of structures that are visible |
*Regional Anatomy* | Studying structures in each region. |
*Systemic Anatomy* | Study of Organ System by Organ System |
Microscopic Anatomy | Study of "micro" Organism. |
Cytology | Cell Study |
Histology | Tissue Study |
Physiology | Function Study |
6 levels of Organization | Cells, Tissue, Organs, Organ Systems, and Organism |
Smallest living Organism; 200 types | Cells |
Tissue | Group of cells that perform part of the function |
One or more tissues makes------ & performs "specific" function | Organs |
Organ System | Multiple Organs Peforming "multiple" Function |
All Organ System Function together to survive and Reproduce | Organism |
Main Cells | Skin cells, Red Blood cells, Nerve cells, Muscle Cells |
Function of Skin cells | Creates a barrier to protect you from bacteria and infections |
Function of Red Blood cells | Carries Oxygen |
Function of Nerve Cells vs Function of Muscle cells | (Nerve)Transmit signals Contracts and Gets Shorter(muscle) |
Thoracic | Chest |
Abdominal | Abdomen |
Antebrachial | Forearm |
Axillary | Armpit |
Brachial | Arm |
Carpal | Wrist |
Cephalic | Head |
Cervical | Neck |
Crural | Leg |
Femoral | Thigh |
Gluteal | Butt |
Inguinal | Groin |
Lumbar | Loin |
Manual | Hand |
Patellar | Kneecap |
Pedal | Foot |
Pelvic | Pelvis |
Pubic | Pubis |
Sacral | Sacrum |
Sural | Calf |
Tarsal | Ankle |
Superior | Towards the Head |
Inferior | Towards the Feet |
Medial | Towards the Midline of the body |
Lateral | Away from the Midline |
Proximal | Closer to the Point of Origin |
Distal | Away from the Point of Origin |
Anterior(Ventral) | Towards the Belly |
Posterior(Dorsal) | Back |
Superficial | the surface of the body Example: Ribs are Superficial to the Liver |
Deep | away from surface |
Transverse Plane | PLANE runs parallel to the ground and divides the body into superior and inferior portions. |
Frontal Plane | (ant on a post)A vertical plane that divides the body or organ into anterior and posterior portions |
Sagittal Plane | Cuts the body into Left and right sides |
Mid Sagittal Plane | Exactly at the Midline; A Vertical Plane that divides the body into equal right and left sides |
Para Sagittal Plane | A vertical plane that divides the body or organ into unequal right and left sides |
Dorsal Body Cavity | (Doors- in-the- back) Subdivided into a cranial cavity (contains brain) and Vertebral cavity(contains Spinal Cord); Located near the Posterior surface of the body. (back) |
Ventral Body Cavity | Located in the Anterior part of the body; Subdivided into Thoracic and AbdominoPelvic cavity by the diaphragm |
What Makes Cavity? | Membranes |
Organs inside the Ventral Cavity is called | Viscera |
Thoracic Cavity | Surrounded by ribs and muscles of the chest; It is subdivided into Pleural Cavity and Mediastinum. |
Pleural Cavity | 2 of them; contains lungs |
Mediastinum | Not a cavity; It's a mass of tissue that extends from the sternum to Vertebral column; It contains the Pericardial Cavity; Also contains thymus, aorta and esophagus |
Pericardial Cavity | Contains the heart |
Visceral Pleura | Covers the wall of the Organ |
Parietal Pleura | On the outisde |
Cavity | Space between Visceral and Parietal Pleura |
