Skin- Integumentary System Terms to know related to this section:Cutane or derm skinXer dryKeratinized: hard, waterproof proteinSquamous: squished, flattened cellsCollagen: a protein that provides structural supportOnych nailsAdip fatMelanin: skin pigmentThe cutaneous membrane, skin, is a dry membrane which is composed of keratinized stratified squamous epithelium and collagen.Skin derivatives – sweat glands, oil glands, hair nailsProtects deeper tissue from: bumps, chemicals, bacteria, UV rays, heat ect.Skin functions (Physiology) – protects the body, aids in heat loss retention, excretion of toxin, synthesizes vitaminMelanocytes release what is called melanin. This creates the pigment of your skin. The sun stimulates the melanocytes to produce more resulting in a tan.Parts of the SkinLayers of the skin:Epidermis- Outer most layer (superficial) contains our pores and hair shaftDermis- Middle layer composed of hair follicles, oil glands, sweat glands, nerves, etc.Hypodermis- Inner most layer (deep) contains adipose tissue or fat The bottom layer of the skin is the hypodermis where adipocytes create this: sweat fat skin cells blood Label the parts of the skin diagram epidermis dermis hypodermis sebaceous oil gland eccrine sweat gland adipose Match the term to the definition. derm skin onych nails adip fat melanin pigment Sensory Organs Parts of the eye:Terms to know related to the eye:blephar eyelidlacrim tearsopia: visual disorderDisorders related to the eye:Nearsightedness or Myopia: the image is formed in front of the retina instead of on it due to a lens defectFarsightedness or Hyperopia: is a defect of vision in which closer objects appear to be blurred.Diplopia: double visionGlaucoma: disease of the eye marked by increased pressureXerophthalmia: dry eyesNyctalopia: condition of night blindnessKeratoplasty: surgical repair of the corneaParts of the Ear:Terms to know related to the ear:Tympan or myring tympanic membrane or eardrumCerumen: earwaxDisorders of the ear:Tinnitus: ringing of the earDeafness: inability to hear Audiometer: measure hearing loss Match the picture to the disorder myopia hyperopia glaucoma tinnitus Label the parts of the eye cornea lens optic nerve pupil sclera Label the parts of the ear auricle auditory tube stapes tympanic membrane cochlea auditory nerve
