Tissues
This term describes an increase in the size of existing cells within a tissue, such as in skeletal muscle during weight lifting
Hypertrophy
This process, occurring in red bone marrow, is responsible for the production of all blood cells.
Hematopoiesis
This region of a long bone is the elongated, cylindrical shaft.
Diaphysis
This is the most superficial layer of the epidermis, consisting of 20 to 30 layers of dead, scaly, keratinized cells.
Stratum Corneum
This type of joint is freely mobile and contains a fluid-filled capsule.
Synovial Joint
This type of muscle tissue is striated, branched, and contains intercalated discs.
These mature bone cells reside in small spaces called lacunae and maintain the bone matrix.
Osteocytes
This type of bone growth occurs within the periosteum and results in an increase in the bone's width.
Appositional growth
These cells, found in the stratum basale, produce the pigment that protects the skin from UV radiation.
Melanocytes
These bands of dense regular connective tissue connect bone to bone and provide stability to joints.
Ligaments
These specialized epithelial cells are found in simple columnar and pseudostratified columnar tissues and are responsible for secreting mucin
These large, multinucleated cells are responsible for bone resorption by secreting hydrochloric acid and enzymes
Osteoclasts
This type of cell junction acts like "spot welds" between cells, providing resistance to mechanical stress at a single point.
Desmosomes
This protein, found in the epidermis, hair, and nails, provides strength and water-resistance to the skin.
Keratin
These bands connect bone to muscle
Tendons
This type of exocrine gland releases its secretions by pinching off the apical portion of its cells
Apocrine gland
This condition, common in the elderly, involves a reduction in bone mass sufficient to compromise normal function.
Osteoporosis
This double-layered membrane covers the external surface of bones and is attached by perforating fibers.
Periosteum
This hormone is released by the parathyroid glands when blood calcium levels are too low.
PTH (Parathyroid Hormone)
This specific type of synovial joint, like the elbow or knee, allows for movement in only one plane.
Hinge Joint
this term refers to an increase in the total number of cells in a tissue.
Hyperplasia
This hormone, released by the thyroid gland, helps decrease blood calcium levels by inhibiting osteoclasts.
Calcitonin
These "soft spots" on a baby's head allow for brain growth and easier passage through the birth canal.
Fontanelles
These tactile cells, located in the stratum basale, are sensitive to touch and release chemicals that stimulate sensory nerve endings
Merkel Cells
This term describes the movement of a limb away from the midline of the body.
