Mitosis and Tissues Flashcards
List the phases of mitosis (M phase)and explain the major events of each one
The nucleus actively divides in four phases. (Prophase Metaphase, Anaphase, & Telophase.)
Describe the sub phases of interphase.
Interphase is divided into 3 states, G1 ( cell only has one copy and of it’s DNA and it gathering nutrients and protien for the next phase.. -S the synthesis phase cells duplicate their nucleus in DNA which remains packages in chromatin and centrosomes and G2 the cell continues to grow and multiply organelles and protein that are required for mitosis and replenish their energy . The cell is growing , maturing, and differentiating.

Epithelial tissue: how it is classified, different types and main organs where you can find it.
It’s classified based on the number of layers of the cell like Simple (one layer of cells) epithelial and Stratified (two or more layer of cells.) second classifications is the cell shape (Squamous are flat cells, cube shaped is cuboidal, and columnar of they are shaped like columns. Pseudostratified just one layer, but seems like there are more cells. . Transitional change shape from flat to cuboidal shapes( found urinary bladder) 8 types of Epithelial tissue.
Connective tissue: function and general composition, classification and locations.
Loose connective tissue: Areloar, adipose, reticular. Dense connective tissue: regular, irregular and elastic. All types are gel like ground substances. Their function is acting a binding tissues, resist mechanical stress, particularly tension.
Muscular tissue describe the 3 different types and main characteristic of each one :
skeletal (attach to bones) muscle, smooth muscle (hollow organs) , cardiac muscle (in the heart).
Nervous tissue: function and general composition; type of cells and locations.
The nervous tissue is the primary component of the brain, spinal cord and peripheral nerves. There are two main cell types: Neurons and Neurological cells. Neurons have a cell body (where the nucleus and organelles like Nissil bodies.) The dendrites, are like arm like and extend of the cell body, they receive messages from other neurons and also from the axon which send messages to other neurons, muscle cells or gland cells. The smaller and more numerous cells around the neurons are the neuroglial cells The six different types of neuroglial cells vary significantly in shape and appearance. Neuroglial cells in general perform func-tions that support the neurons or the ECM.
