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 |
