Introduction to Anatomy
this kind of plane divides the body into anterior and posterior sides
what is the frontal plane?
blood belongs to this category of tissue (there are 4 main categories of tissues)
what is connective tissue?
this material makes up your skin and nails, and makes your epidermis dry/hard
what is keratin?
this is the number of bones we have in our body (usually)
what is 206?
this hormone is secreted to increase Ca blood levels and increase osteoclast activity
what is parathyroid hormone PTH?
located in the ventral cavity, these cavities contain your lungs
what are the pleural cavities?
the intervertebral discs are made of _____cartilage and the ear & epiglottis are made of _____ cartilage
what are fibrocartilage and elastic cartilage?
this degree of burn occurs when there is damage to the entire epidermis but only the upper dermal layer is damaged
what is a second degree burn?
the skull has _____ bones and the patella is classified as a _____ bone
what is flat bones and short (sesamoid more specifically) bone?
interstitial growth/bone lengthening occurs at this site on a long bone. this bone lengthening occurs during childhood and adolesence.
what is the epiphyseal plate/line?
calcium level regulation with parathyroid hormone and calcitonin is an example of what this kind of feedback mechanism
what is negative feedback?
this is a kind of connective tissue found in the tendons, ligaments, and aponeuroses
what is dense regular tissue?
this type of cutaneous gland lubricates the skin, is connected to the hair follicle, and secretes oily sebum
what is a sebaceous gland?
this kind of bone cell is multinucleated, derived from macrophages, and breaks down bone.
what is osteoclast? (be able to recognize visual differences between the bone cells for exam)
____________ growth occurs when the bone grows wider and thickens due to mechanical stress/weight. bone is secreted on the external surface of the bone
what is appositional growth?
this is an example of a positive feedback mechanism
what is baby delivery or platelet clotting?
usually containing goblet cells, this type of epithelial tissue can be found in the digestive tract, bronchi, uterine tubes, and uterus. they may also have microvilli and cilia
what is simple columnar epithelium?
this is the order of epidermal skin layers (in thick skin) from superficial to deep [do you know the acronym?]
stratum corneum, lucidum, granulosum, spinosum, basale
made of calcium phosphate crystals, this inorganic material composes 65% of the chemical composition of a bone
what is hydroxyapatite?
in endochondral ossification, the ______ _______ ______ can be found in the epiphyses of the long bone which develops into spongy bone. this occurs during fetal development. (3 words)
these are the three medial regions of the abdominopelvic area from superior to inferior (remember the tic-tac-toe formation)
what are epigastric, umbilical, and hypogastric?
this kind of muscle is striated and contains intercalated discs
what is cardiac muscle?
this kind of skin cancer is the most malignant and is difficult to treat. health professionals use the ABCD rule to analyze a suspicious mole
what is melanoma?
in an adult, red marrow is only found in the epiphysis of these long bones
what are the femur and humerus?
in intramembranous ossification, ______ cells differentiate into osteoblasts to create the ossification center. _______ bone is formed and is replaced by lamellar/compact bone
what are mesenchymal cells and woven bone?
