Tissue Classification:

Tissue Classification:

Areolar Tissue, fibrous

Cells are known as “fibroblasts”

elastin also appears

Tissue Classification:

Connective tissue, bone

Cells are known as “osteocytes”

Haversian Systems- archery/rifile targets

tiny canals that connect the cells to the blood- canaliculi which are found in cavities called lacunae

What cell morphology is shown?

columnar epithelium

What tissue is this

Muscle, smooth specifically

rhythmic contraction- peristalsis (involuntary)

What tissue is this

Muscle, striated specifically

rythmic contraction- contractile (voluntary)

Epithelial Morphology Types (3)

1. Squamous

2. Cuboidal

3. Columnar

Tissue Classification:

Connective tissue, blood

Matrix- plasma (liquid portion)

Red cells known as “bioncave”, erythrocytes

In bone marrow- hemopoietic tissue

Tissue Classification:

Connective, Cartilage

Cells known as “chondrocytes”

Matrix secreted- chrondrin

LACK - blood vessles

Cell-to-cell attachment features among tissues (2)

1. cell membrane junctional complexes

2. matrix secretion

What kind of tissue class

Muscle, specifically cardiac

Roots, Stems and Leaves together

Stem

Leaves

Roots

Secondary growth - cambiun

Secondary growth is responsible for the increase in circumference in woody plants and arises from meristematic tissue called cambium.

Xylem vs Phloem

Xylem- Dead, water & nutrients

Phloem- Living, carbs (food)

Terms used for describing baceterial colonies

Mushroom fungi labled

top of mushroom- pileus

stalk of mushroom - stipe

gills

mushroom fungi gills labled

Flower parts labled
