3. Structure?

4. Function?

1. Areolar (Loose) Connective Tissue

2. Under epithelia, connect to nearby structures

3. Loosely packed/arranged fibers, fibrocytes, ground substance

4. Allows for flexible movement (stretching) & transport of materials throughout the tissue (exchange)

3. Function?

1. Skin: Epidermis (Epithelial: Keratinized Stratified Squamous) & Dermis (Connective Tissue: Loose connective & Dense irregular)

2. Layered cells = protection/barrier
   Loose, different directions of fibers = resists pull moderately

4. Function?

1. Adipose connective tissue

2. Beneath skin, around organs

3. Cell filled with a droplet of lipid, pushing nucleus to plasma membrane. Not much matrix

4. Storage (lipids), cushioning, insulate (traps body heat, prevent too much heat)

3. Structure?

4. Function?

1. Dense regular connective (Tendon)

2. Between skeletal muscle & bone

3. Tightly packed thick bundles of fibers, very dense matrix, cells occupy the space between fibers, same direction, parallel

4. Transmit force/a pull along the direction of fibers. Like, skeletal muscle force to the tendon then to bone for the arm to move

4. Function?

1. Hyaline cartilage connective tissue

2. End of bone with moveable joints

3. Cartilage cells sit in lacunae. Large matrix

4. Reduce friction & compression of joints

2. Location?

3. Structure?

4. Function?

1. Skeletal muscle

2. Connects to tendon & bone

3. Muscle fibers (living cells) that are organized, long, and parallel to one another. Striations are the lines on the fibers and are the arrangement of the contractile proteins. They produce the force.

4. The fibers can shorten & pass force onto the tendon

2. Location?

3. Structure?

4. Function?

1. Compact bone

2. outer part of bone

3. organized mineral matrix & osteocytes within lacunae. central canals as well

4. the mineralized matrix supports the body & force. the central canals are for blood vessels to supply nutrient to the compact bone through diffusion to nearby osteocytes

3. Structure?

4. Function?

1. Pseudostratified Ciliated Columnar epithelium

2. Lining trachea

3. Tall cells that look like stratified. All the cells reach basement membrane, some dont reach the surface.Cilia at the surface

4. Cilia move mucus along in a beat, waving rhythm

4. Function?

1. Reticular connective tissue

2. supporting framework for lymph nodes

3. network of fibers, supporting framework, net/mesh-like

4. Support the cells in soft organs

3. Structure?

4. Function?

1. Simple columnar epithelium

2. Lining of small intestine

3. single layer of tall cells, microvilli on top

4. large absorption area, more cytoplasm for organelles for secretion

4. Function?

1. Nervous tissue

2. Brain, spinal cord

3. Big neurons & glial cells

4. The neurons carry signals between one another. Glial cells help regulate the environment/support neurons.

4. Function?

1. Simple cuboidal epithelium

2. Lining thyroid follicles

3. One layer of cuboidal cells, on the surface of some substance

4. Promote exchange of materials & secretion
