1 Do Now 8/18/14 What body cavity contains the reproductive organs? Be as specific as possible. What are the two main divisions of body cavities? The patellar region is ________ to the tarsal region. (medial/lateral/proximal/distal) The thoracic region is ________ to the femoral region. (anterior/posterior/superior/inferior) The nose is _______ to the ear. (medial/lateral/proximal/distal)

2 4 types of tissues 1. epithelial tissue 2. connective tissue
3. muscle tissue 4. nervous tissue

3 Epithelial tissue includes…
1. layers of cells that cover internal or external surfaces 2. glands

4 Some important characteristics are…
1. cells are close together 2. a free surface exposed to environment or internal chamber/passageway. 3. attachment to basement membrane provides barrier 4. no blood vessels (avascular) 5. continually replaced and regenerated

5 Functions of epithelia…
1. Provide physical protection 2. Control permeability What comes in and out 3. provide sensation 4. produce specialized secretions Exocrine= secretions released to surface of skin Endocrine= secretions released as hormones into tissue fluid & blood

6 Epithelial cells are classified by amount of layers and shape…
Simple = one layer stratified = multiple layers Pseudostratified = looks like multiple layers Squamous = thin/flat Cuboidal = shaped like a cube or hexagon (6) Columnar = long and skinny Ciliated = contain cilia

7 An example… One layer with tall and skinny cells
Simple columnar Multi-layered and square shaped Stratified cuboidal

8 Pseudostratified Ciliated Columnar
Location: respiratory tract (nasal cavity, larynx, trachea, bronchi) Function: cilia moves mucus across the surface of the cells, protection

9 Glands Endocrine glands – secrete hormones directly into the bloodstream Hormones are chemical messengers that influence cells in the rest of the body Exocrine glands – use different processes to release secretions Ex: sweat glands, mammary glands, salivary glands

10 Station Expectations One group at each station 2 min at each station
Rotate clockwise

11 The purposes of Connective Tissue…
Bind (hold things together) Support & protect Fill spaces Store fat Produce blood cells

12 Locations: Facts: Widely distributed throughout the body
Good blood supply Farther apart than epithelial cells Connected with matrix

13 Classification of Connective Tissue
Connective tissue proper Loose connective tissue Areolar Adipose Reticular Dense connective tissue Supporting connective tissue Cartilage Bone Fluid connective tissue Blood

14 1.a. Loose Connective Tissue
lies under skin, connect it to organs, provides blood supply The body’s “packing material”

15 1.a.i. Areolar Function: Protects tissues and organs, binds epithelia to deeper tissue Location: dermis (skin)

16 1.a.ii. Adipose Function: stores energy, insulates & cushions
Location: subcutaneous layer (deep to skin), surrounding organs

17 1.a.iii. Reticular Function: provides support to lymphatic system organs Location: spleen, lymph nodes, thymus, bone marrow

18 1.b. Dense Connective Tissue
very STRONG, used to bind parts together Function: attaches bone to bone (ligaments), muscle to bone (tendon) Location: ligaments, tendons

19 1.b. Dense Connective Tissue
Ligaments Connects BONE to BONE Tendons Connect MUSCLES to bone

20 2.a. Cartilage Function: Protects, absorbs shock (in joints)
Location: tip of nose, ends of long bones, intervertebral discs, external ear

21 2.b. Bone very rigid, heals quicker than cartilage
Function: provides support (more than cartilage) and levers for movement Location: bones of the body

22 3.a. Blood Function: helps transport and maintain internal environment
Location: blood vessels, heart

23 Flashcards Make Flashcards for the types of Epithelial and Connective Tissue FRONT BACK Name of tissue Function Picture

24 Exit 1. a single layer of cells that are thin and flat are called:
2. a multi-layered group of cells that are long and skinny are: 3. a single layer of square cells 4. What connective tissue is responsible for storage of energy?
