Animal Tissues Flashcards
- fat cells
- contain vacuole, large vacuoles
- nasa side si nucleus
- fillers and insulates
Adipose tissue
Mineralized connective tissue made by bone-forming cells called osteoblasts which deposit collagen
Bone
- Compact arrangement of cells
- Presence of basement membrane
- Avascular (no blood supply)
- polarized
Epithelial Tissue
Function of Simple Cuboidal
Secretion and absorption
Stipes, voluntary movement, like tendons - attaches to bones)
Skeletal tissue
Function of Stratified Cuboidal
Protection
transmission (transmit and receive) of impulses from one part of the body to the other parts
Nervous tissue
Function of Stratified Columnar
Protection
Involuntary movements, movement of the esophagus, spindle shape
Smooth tissue
Provides strength and flexibility
Collagenous
Blood clotting
Platelet
Neurons
Axons - send or away signals
Demdrites - towards or receive signals
- absence of nucleus to store/carry oxygen (hemoglogen)
Red blood cell
Dense fibrous tissue
Ligaments (bone to bone)
Tendons (bone to skeletal muscle)
- With elongated cells (muscle fibers) specialized for contraction to produce movement
- Important in holding the body stable
Muscle tissue
Epithelial Tissue (named by LAYERS)
Simple - 1 layer
Stratified - Multiple layers
Pseudostratified - 1 layer but looks many
Function of Simple Squamous
Diffusion and Filtration
Epithelial Tissue (named by SHAPE)
Squamous - Flat-sheet like, scale
Cuboidal - Cube
Columnar - Coluimn
Connective tissue types
Dense CT
Loose CT
Bone
Blood
Adipose
Cartilage
can be found in spine, between vertebrae
Fibrocartilage
exclusive to heart, stripes, intercalated disk is present (for synchronized heart contraction), involuntary
Cardiac tissue
Under blood
Red blood cell (RBC)
White blood cell (WBC)
Platelet
Cushion between bones
Cartilage
Connective tissue fiber types
Collagenous
Reticular
Elastic
varying amounts of extracellular matrix (ground substance and fibers)
Connective tissue
defend against pathogen (immune system)
White blood cell
Nourishes neurons
Glia
Elasticity (returns to original form)
Elastic
Binds connective tissues
Reticular
Made up of plasma (liquid extracellular matrix); contains water, salts, and dissolved proteins
Blood
Function of Stratified Squamous
Protection
Function of Simple Columnar
Secretion and absorption
can be found in intercostal ribs and trachea
Hyaline
collagen fiber/collagenous (arrange in concenrix rings called lamella)
Bone
- in ear
- maintains shape of a structure while allowing great flexibility
Elastic cartilage
