| Question | Answer |
|---|---|
| Which junction is required for cell-to-cell communication? | Gap junctions |
| Epithelial cells that are adapted for absorption usually have ________ at their free surface. | Microvilli |
| A type of intercellular junction that stops materials from crossing an epithelium between cells is called a | Tight junction |
| Dead skin is shed as thin sheets of interlocked cells, instead of as individual cells, because ________ create permanent connections between each cell. | Desmosomes |
| Epithelium is connected to underlying connective tissue by | Basement membrane |
| In stratified epithelia adapted to resist mechanical forces, which of the following types of cell-to-cell junctions are especially abundant? | Desmosomes |
| In stratified epithelia adapted to resist mechanical forces, which of the following types of cell-to-cell junctions are especially abundant? | epithelial tissue |
| Which epithelium, is responsible for protection, secretion, and absorption? | stratified cuboidal |
| Which epithelium, shown at the end of the arrow, is responsible for protection, secretion, and absorption? | Holocrine glands |
| The function of simple cuboidal epithelium is | Absorption and secretion |
| __________ provide strength in many directions | Dense irregular connective tissues |
| classified as "connective tissue proper"? | - Reticular - Adipose - collagen |
| Cells that store fat are called | adipocytes. |
| The internal framework or stroma of organs such as the spleen, liver, and lymph nodes is made up of ________ tissue. | Reticular tissue |
| The three categories of connective tissues are | proper, fluid, and supporting. |
| The three types of protein fibers in connective tissue are | collagen, reticular, and elastic |
| Loose connective tissue functions in | filling spaces between organs. anchoring blood vessels and nerves. cushioning and stabilizing. supporting epithelia. |
| Osseous tissue is also called | bone |
| Which type of connective tissue is found in the trachea and between the ribs and sternum? | Hyaline cartilage |
| A tissue with a firm gel matrix and cells inside lacunae is | cartilage |
| Unlike cartilage, bone | undergoes remodeling throughout life. |
| The serous membrane covering the lungs is the | pleura |
| Which of the following membranes line cavities that communicate with the exterior of the body? | mucous |
| The framework of connective tissue between the skin and underlying muscles is called the | superficial fascia. |
| Intercalated discs and pacemaker cells are characteristic of ________ tissue | Cardiac muscle |
| Which structure typically receives information from other neurons | dendrite |
| Myosatellite cells are found within __________ muscle | Skeletal |
| The type of muscle tissue that does not contain gap junctions is __________. | Skeletal |
| Which formed element of the blood contains a nucleus? | white blood cells |
| The watery fluid component of blood is called | plasma. |
| What type of cell makes up almost half the volume of blood? | RBC |
| Defense cells in blood are called white blood cells or | Leukocytes |
| Which blood vessels have porous walls that allow water and small solutes to seep through? | Capillaries |
| To celebrate her 50th birthday, Anna got her ear pierced in the elastic cartilage portion (pinna). The piercing specialist informed her that it will take at least 6 weeks to heal. This is because | cartilage is avascular, so healing takes longer |
| Antiangiogenesis factor is produced by ________ to block the growth of blood vessels | chondrocyte |
| Tendons and ligaments attach to the ________ of bone | periosteum |
| Between each vertebra of the spinal column, there is a tough pad of | fibrocartilage |
| Which muscle tissue consists of multinucleate cells? | skeletal muscle |
| The muscle found in the walls of most hollow organs of the body is | smooth muscle |
| glands possess ducts that transport secretions onto epithelial surfaces. | Exocrine |
| Glands that secrete hormones into the blood are | endocrine glands |
| The function of microvilli on the apical membrane of transporting epithelia is to | increase the cell's surface area. |
| The simple squamous epithelial lining of blood vessels is called | endothelium. |
| The distinguishing characteristic of connective tissue is | the presence of extensive extracellular matrix containing widely scattered cells. |
| Which organ system is lined by transitional epithelium to accommodate stretchin | urinary system |
| What type of secretion involves the release of substances, such as saliva and sweat, in secretory vesicles by exocytosis? | merocrine |
| Tumors in the nervous system would involve | neuroglial cells because they are capable of mitosis Neuroglial cells are small, supportive cells surrounding the neurons in nervous tissue. Neuroglial cells have many functions and can go through mitosis. |
