뒤로Lab Cells and Epithelium
이 집합의 용어 (34)
Ribosomes
Protein Synthesis
Endoplasmic Retriculum (ER)
Storage and transport of the proteins. Steroid and lipid synthesis
Golgi Apparatus
Packaging Proteins
Lysosomes
Digestive enzymes
Peroxisomes
detoxify
Mitochondria
"powerhouse of the cell". Produce cellular energy
Centrioles
Direct the formation of the mitotic spindle
Cytoskeletal elements: microfilaments, intermediate filaments, and microtubules
Provides cellular support, mobility
Prophase
Chromosomes become visible, nuclear membrane and nucleoclus disappear, centrioles move apart, spindle fibers form
Metaphase
Chromosomes line up in the center of the cell and are attached to spindle fibers
Anaphase (mitosis)
Cenromerers split apart as the spindle fibers shorten and pull chromatids to opposite sides
Telophase (mitosis)
Cytoplasm is divided (cytokinesis) and cells separate, new nuclear membrane and nucleolus appears, chromosomes lengthen
Epithelial Tissue
Covering
Connective Tissue
Support
Muscle Tissue
Movement
All epithelial tissues have 2 names. What are they?
First: indicates number of cell layers (simple, stratified)
Second: indicates shape of cells (squamous, cuboidal, columnar)
Simple Squamous
Location: Alveoli of lung
Function: Diffusion & Filtration
Simple Cuboidal
Location: kidney tubules
Function: secretion & absorbtion
Simple Columnar
Location: Digestive tract
Function secretion of mucous/absorbtion
Stratified Squamos
Location: Epidermis of skin
Function: protects from abrasion
Transitional
Location: Urinary bladder
Function: stretches
Psuedostratified Ciliated Columnar
Location: Trachae
Function: produces and moves mucus
Skeletal Muscle
Location: skeletal muscle
Function: volentary movement
Cardiac Muscle
Location: heart
Function: pumps blood
Smooth Muscle
Location: hollow organs
Function: Involuntary movment of substances
Blood (Connective Tissue)
Location: blood vessels
Function: transports gases and nutrients
Bone (Connective Tissue)
Location: Bones
Function: supports, protects, allows movement by muscle
Fibrocartilage (Connective Tissue)
Location: Intervertebral discs
Function: shock absorber
Dense Regular (Connective Tissue)
Location: Tendons
Function: connects muscle to bone
Areolar (Connective Tissue)
Location: Under epithelial tissue thoughout body
Function: wraps and cushions tissues organs
Adipose (Connective Tissue)
Location: fat
Function: energy storage, insulation, and protection
Elastic (Connective Tissue)
Location: Aorta
Function: recoils if stretched
Nervous Tissue (Nervous)
Location: brain, spinal cord, nerves
Function: transmit electrical signals
Nervous Tissue
Control
