| Term | Definition |
|---|---|
| Anatomy & Physiology | Anatomy is the structure of the body. Physiology is the function of the body. |
| Macroscopic & Microscopic | Macroscopic is visible to the naked eye Microscopic is not visible to the naked eye. |
| Cytology & Histology | Cytology is the study of the cells, especially their appearance and structure. Histology is the study of tissues and cells under a microscope. |
| Levels of organisation | Atoms, Molecules, Organelles, Cells, Tissue, Organs, Organ System, Organism |
| Types of tissue & how many types? | Four - Epithelial Tissue, Connective Tissue, Muscle Tissue, Nervous Tissue |
| Epithelial Tissue | Form the coverings and linings of the body |
| Connective Tissue | supports and protects body organs |
| Muscle Tissue | contracts to move the whole body, or move substances through the body |
| Nervous Tissue | creates and transmits electrical impulses allowing communication within the body. |
| Organ Systems | Murders Linc - Muscular, Urinary, Reproductive, Digestive, Endocrine, Respiratory, Lymphatic, Integumentary, Nervous, Circulatory |
| Integumentary System | Hair, Skin & Nails External physical barrier - protecting your body from bacteria, infection, injury and sunlight. Makes vitamin D. |
| Musculoskeletal System | Bones, Connective tissue, Joints. Body's framework, allowing movement of limbs & whole body. Also produces heat & stores calcium. |
| Endocrine System | Pineal, Pituitary, Parathyroid, Thyroid & Adrenal Gland - Hypothalamus, Pancreas, Ovary & Testis Produces and secretes hormones that regulate body process such as reproduction, metabolism & growth |
| Cardiovascular System | Heart & Blood Vessels Transports blood providing oxygen & nutrients to cells & removes carbon dioxide & wastes |
| Lymphatic / Immune System | Red bone marrow, Thymus, Lymphatic Vessels, Thoracic Duct, Spleen, Lymph Nodes Returns leaked fluids tp the blood. Protects the body against infection & foreign substances. |
| Respiratory System | Nasal Cavity, Pharynx, Larynx, Trachea, Bronchus, Lung Adds oxygen & removes carbon dioxide from the blood |
| Digestive System | Oral Cavity, Esophagus, Liver, Stomach, Small & Large Intestine, Rectum, Anus Breaks down & absorbs nutrients from food |
| Urinary System | Kidney, Ureter, Urinary Bladder, Urethra Regulates the volume and composition of the blood & removes wastes |
| Reproductive System | Mammary glands (in breasts), Ovaries, Fallopian Tubes, Uterus, Uterine Tube, Cervix & Vagina Prostate, Penis, Testis, Ductus Deferens & Scrotum Produces sex cells & hormones. Where foetal development & milk production occur |
| Planes | Frontal, Sagittal & Transverse |
| Frontal Plane | Anterior & Posterior |
| Sagittal Plane | Left & Right |
| Transverse | Superior & Inferior |
| Anatomical Position | Standing facing forward, arms by sides, palms facing forward, thumbs pointing away from body, feet flat on floor - slightly apart & directed forward |
| Directional Terms | Used to describe the location of one body part in relation to another. Superior, Inferior, Medial, Lateral, Proximal, Distal, Anterior, Posterior, Superficial, Deep |
| Superior (Cranial) | Above, higher or closer to head |
| Inferior (Caudal) | Below, lower, away from the head |
| Medial | Towards the midline of the body |
| Lateral | Away from the midline |
| Proximal | Closer to the point of origin (where limb attaches to torso) |
| Distal | Further from the point of origin (where limb attaches to torso) |
| Anterior (Ventral) | In front of, towards the front of the body |
| Posterior (Dorsal) | Behind, toward the back of the body |
| Superficial | Closer to the surface, more external |
| Deep | Away from the surface, more internal |
| Planes of Division | Sagittal, Frontal |
| Sagittal Plane | Creates left & right parts When divides body into equal left & right parts can be called Median Plane or Midsagittal Plane |
| Frontal Plane | Creates anterior & posterior parts |
| Horizontal Plane | Creates superior & inferior parts |
