Study Notes
Body Regions
- Anterior body regions include: Cephalic (head), Frontal (forehead), Orbital (eye cavity), Buccal (cheek), Mental (chin), Sternal, Pectoral (chest), Costal (ribs), Umbilical (navel), Inguinal (groin), Pelvic, Coxal (hip), Acromial (shoulder), Axillary (armpit), Mammary (breast), Brachial (arm), Antecubital (front of elbow), Abdominal (abdomen), Celiac, Antebrachial (forearm), Carpal (wrist), Palmar (palm), Digital (fingers/toes), Genital (reproductive organs), Patellar (front of knee), Sural (calf), Tarsal (instep).
- Posterior regions are: Occipital (back of head), Vertebral (spinal column), Brachial (arm), Dorsal (back), Cubital (elbow), Lumbar (lower back), Sacral (between hips), Gluteal (buttocks), Perineal, Femoral (thigh), Popliteal (back of knee), Crural (leg), Pedal (foot), Plantar (sole).
Other Body Functions
- Food provides energy, builds new matter, and regulates chemical reactions.
- Pelvic cavity contains internal reproductive organs and the urinary bladder, surrounded by pelvic bones.
Mechanisms for Homeostasis
- Internal environment is monitored by:
- Receptors that detect stimuli.
- Control Centers that set acceptable values.
- Effectors that enact changes in response.
- Negative feedback loops regulate homeostasis by opposing changes; signals are sent to reverse stimuli.
- Positive feedback amplifies changes, increasing stimulus.
Levels of Organization
- The biological hierarchy includes: Atom, Molecule, Macromolecule, Organelle, Cell, Tissue, Organ, Organism, Organ System.
Body Cavities and Organ Systems
- Appendicular portion includes upper and lower limbs; Axial portion includes the head, neck, and trunk.
- Major body cavities: Cranial, Dorsal, Vertebral canal, Ventral, Thoracic, Abdominal, Pelvic, and Abdominal-Pelvic.
Describing Lungs
- Lungs are housed in Right and Left pleural cavities and separated by the Mediastinum including the Pericardial cavity.
Cavity and Organ Systems
- Major cavities: Cranial, Vertebral, Mediastinum, Abdominal, Pelvic.
- Major organs (Viscera) include:
- Brain, Spinal Cord, Heart, Esophagus, Trachea, Thyroid, Stomach, Liver, Kidneys, Intestines, Reproductive organs.
Membranes in Thoracic and Abdominopelvic Areas
- Thoracic membranes: Visceral and Parietal Pleura (around lungs), Visceral and Parietal Pericardium (around heart).
- Abdominopelvic membranes: Visceral Peritoneum (covers organs), Parietal Peritoneum (lines cavity).
Organ System Functions
- Functions encompass Support and Movement, Integration and Coordination, Transport, Absorption, and Excretion.
- The primary organ systems include: Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Digestive, Respiratory, and Urinary.
Characteristics of Life
- Life involves: Movement, Responsiveness, Growth, Reproduction, Respiration, Digestion, Absorption, Circulation, Assimilation, and Excretion.
Requirements for Organisms
- Essential elements include: Water (H2O), Food, Oxygen, Heat, Pressure for metabolic processes.
Homeostasis Importance
- Maintenance of a stable internal environment is crucial for the body, requiring feedback mechanisms for regulation.
Reproductive Systems
- Female reproductive system consists of: Ovaries, Uterine tubes, Uterus, Vagina, Clitoris, Vulva.
- Male reproductive system includes: Scrotum, Testes, Epididymides, Vasa deferentia, Seminal vesicles, Prostate gland, Bulbourethral glands, Penis, Urethra.
Anatomical Terminology
- Anatomical position: Standing erect, face forward, arms at sides, palms forward.
- Directional terms include Superior, Inferior, Anterior (Ventral), Posterior (Dorsal), Medial, Lateral, Proximal, Distal, Superficial, Deep.
Cuts and Incisions
- Types of cuts: Gross (large), Oblique (diagonal), Longitudinal (lengthwise).
- Definitions: Cut is a full separation, Incision is a superficial cut.
Anatomy & Physiology
- Anatomy refers to the structure and organization of body parts; Physiology studies their functions.
- Forms follow functions, illustrating how structures like hands and hearts are shaped for their roles in the body.
