Glands and Bones Glands of the Integument ● Glands= produced from the epidermis ● Endocrine= cells make hormones and release them into the blood system ● Exocrine= secretes substance into a duct that opens onto the epithelium ○ Secretion methods: ■ Merocrine= excretion granule is released by exocytosis → Eccrine Sweat Gland ■ Holocrine= entire cell bursts and contents are expelled → Sebaceous Gland ■ Apocrine= part of the cell breaks off and contents are released → Apocrine Sweat Gland ■ Cytogenous= part of the cell is transferred to another cell → Melanocytes ○ Includes: mucus, saliva, enzymes, waste products, milk ○ Stroma= framework of the gland ○ Parenchyma=functional cells of the gland ● Glands can be unicellular or multicellular ○ Acinar Cell= multicellular; produces ; looks like a cluster of grapes ■ Serous= produces watery serous fluid (sweat, milk,  tears) ■ Mucous= produces mucous ■ Mixed= can create serous and mucous ○ Goblet Cell= unicellular; produces mucus; looks like a water  goblet ● Sebaceous Glands ○ Typical= secretes into hair follicles ○ Sebaceous Follicles= secretes onto skin surface ● Sweat Glands ○ Apocrine= sweat + part of the cell; releases sweat onto the hair  follicle; provides nutrition for bacteria ■ Ceruminous= wax ■ Mammary= milk ○ Merocrine= in reticular part of dermis; carries sweat to surface of  epidermis;  ● Oil Glands ○ Holocrine= Cell explodes to release oil and keep skin from drying;  excretes onto hair follicles or directly onto skin ● Mammary Glands ○ Apocrine= milk is produced into glands and travels through ducts ● Ceruminous Glands ○ Apocrine= glands in ear canal produce wax to prevent against  infection Embryonic Development ● The three layers of the embryo ○ Ectoderm ■ “outside”; forms skin, CNS  ○ Endoderm ■ “inside”; digestive system, lungs ○ Mesoderm ■ “middle”; forms everything else Cartilage and Bone ● Cartilage and Bone are each types of connective tissue ● Cartilage ○ Functions ■ Support soft tissue ■ Gliding surface ■ Basis for some joints ■ Model for bone formation ● Bony precursor that later ossifies  into bone ○ Cartilage Cells ■ Chondrocyte= maintains cartilage ■ Chondroblast= makes cartilage ○ Characteristics ■ Live in lacuna (cell nests) ■ Cartilage matrix includes collagen and ground  substance ■ Cartilage is avascular ■ Cartilage Growth: ● Interstitial growth= growth in length; chondrocytes via mitosis, two daughter cells in one lacuna ● Apposition= growth in diameter;  chondroblasts by creating more cartilage matrix ○ Types of Cartilage ■ Hyaline ● Most common; absence of collagen;  bone precursor ● Articular Cartilage= at bone ends;  absence of perichondrium ■ Elastic Cartilage ● least common; highly flexible;  branched elastic fibers in an irregular pattern ■ Fibrocartilage ● Columns of chondrocytes separated  by dense regular collagen fibers ● Strengthens attachments of tendon  and ligaments ● Prevents stretching and compression ● Shock absorber ● Lacks perichondrium ● Bone ○ Functions ■ Support and protection ■ Movement ■ Hemopoeisis ■ Storage of mineral and energy reserves ● Homeostasis ○ Composition ■ Organic ● Collagen (protein; somewhat  flexible; about 90% of bone’s organic component) ■ Inorganic ● Hydroxyapatite, citrate, fluoride,  strontium ● Rigid ○ Characteristics ■ Bones are flexible and dynamic ■ Vascularized ● Growth, development, remodeling,  regeneration ○ Bone Cells ■ Osteoblasts ● Produce bone; in periosteum and  endosteum; produce osteoid (protein matrix) ■ Osteocytes ● Surrounded by bone; maintain bone  cells; housed in lacunae ● Canaliculi= tiny canals for  communication between cells ■ Osteoclasts ● Destroys bone; large and  multinucleated; helps with remodeling of bone during  reconstruction and heling
