Lab 2 Flashcards
Simple Squamous Epithelium
- Alveoli of lung
- Diffusion and filtration
Simple Cuboidal Epithelium
- Kidney tubules
- secretion and absorption
Simple Columnar Epithelium
- Digestive tract
- Secretion of mucous/absorption
Stratified squamous epithelium
- epidermis of skin
- protects from abrasion
Transitional epithelium
- urinary bladder
- stretches
Pseudostratified ciliated Columnar epithelium
- Trachea
- protects and moves mucous
Skeletal Muscle
- skeletal muscle
- voluntary movement
Cardiac Muscle
- heart
- pumps blood
Smooth muscle
- hollow organs
- involuntary movement is substances
Blood
- blood vessels
- transports gases and nutrients
Bone
- bones
- supports, protects, allows movement by muscle
Fibrocartilage
- intervertebral discs
- shock absorber
Dense regular
- tendons
- connects muscle to bone
Areolar
- Under epithelial tissue throughout body
- wraps and cushions organs
Adipose
- fat
- energy storage, insulation, and protection
Elastic
- aorta
- recoils if stretched
Nervous tissue
- brain, spinal cord, and nerves
- transmit electrical signals
Protein synthesis
Ribosome
- storage and transport of the proteins
- steroid and lipid synthesis
Endoplasmic Reticulum
Packaging proteins
Golgi Apparatus
Digestive enzymes
Lysosomes
Detoxify
Peroxisomes
- produce cellular energy (ATP)
- “power house of the cell”
Mitochondria
Direct the formation of the mitotic spindle
Centrioles
- Provide cellular support
- mobility
Cytoskeletal elements: microfilaments, intermediate filaments, and microtubules
Chromosomes become visible, nuclear membrane and nucleoli is disappear, centrioles move apart spindle fibers form
Prophase
Chromosomes line up in the center of the cell and are attached to spindle fibers
Metaphase
Centromeres split apart as the spindle fibers shorten and pull chromatids to opposite sides
Anaphase
Cytoplasm is divided (cytokinesis) and cells separate, new nuclear membrane and nucleolus appears, chromosomes lengthen
Telophase
Which basic tissue has the function of covering?
Epithelial tissue
Which basic tissue has the function of support?
Connective tissue
Which basic tissue has the function of movement?
Muscle tissue
Which basic tissue has the function of control?
Nervous tissue
Single layer thick
Simple epithelia
Two or more layers thick and involved in protection
Stratified epithelia
Flattened and scale- like
Squamous
Box like, cube
Cuboidal
Tall, column like
Columnar
Stratified epithelial tissues are names for the cell type closest to lumen/surface
Apical
