| Question | Answer |
|---|---|
| three layers of the skin | Epidermis, Dermis, Hypodermis/ subcutis |
| organelles of the cell | Nucleolus, Nucleus, Smooth ER, Rough ER, Mitochondria, Centrioles, Golgi Apparatus, Lysosome, Ribosome, Cytoplasm, Cytoskeleton, Plasma membrane |
| Structures of the eye | Conjunctiva, Cornea, Pupil, Iris, Lens, Vitreous Humor, Retina, Sclera Choroid, Optic Nerve |
| 3 primary Planes of the body | Sagittal(right/left) Coronal/ frontal (front.back), and transverse/axial ( bottom/top) |
| anatomical position | person stands upright, facing forward, with feet together and parallel, arms at their sides, and palms facing forward |
| parts of a neuron | Dendrites, Soma, Axon, Axon terminals |
| Parts of the outer ear | Pinna/ Auricle, Ear Canal, Tympanic Membrane |
| Parts of the middle ear | ossicles, eustachian tube |
| Parts of the inner ear | Cochlea, Vestibule |
| How hearing works | Sound waves enter the outer ear, vibrate the eardrum, are amplified by the ossicles, and travel into the cochlea, where they're converted to electrical signals sent to the brain via the auditory nerve, allowing us to hear. |
| Major endocrine glands -Hypothalamus & pituitary | Brain glands, pituitary is "the master gland" controlling others |
| Major endocrine glands -Pinneal | In the brain, produces melanin to sleep |
| Major endocrine glands -Thyroid & parathyroids | in the neck, regulate metabolism and calcium |
| Major endocrine glands -Adrenals | on kidneys, produce stress hormone (cortisol, adrenaline) |
| Major endocrine glands -Pancreas | behind stomach, makes insulin/ glucagon for blood sugar (also exocrine) |
| Major endocrine glands -Ovaries(females), testes (males) | gonads produce sex hormones |
| Major endocrine glands -Thymus | in the chest, crucial for immune system development |
