Spongeocoel Incurrent Canal Porocytes |
S: Central cavity where excess water collects I: A channel between ostia and porocytes P: Pores within incurrent canal folds that lead to radial canals |
|
Hyaline Cartilage |
Location: Between bones Function: Cushions surfaces of joints |
|
Apopyles Osmium Mesohyl |
A: large opening leading to spongeocoel O: Surface pores that water enters through M: Semi-fluid matrix within sponge |
|
Blastula Stage |
Migration of blastomere to the periphery of the cell; creating a blastocoel |
|
Yolk Plug |
Marks the opening of the blastopore |
|
Vegetal vs. Animal Poles |
Vegetal: Yolk Animal: Embryo |
|
Gastrula Stage |
Autoinvagination (inward folding) into the blastocoel creating an inner cavity; the archenteron |
|
Deuterostome |
First opening is anus, then the mouth EX: explains why humans are shittalkers (joke) |
|
Elastic Cartilage |
Location: Ear, nose, larynx Contains collagen and elastic fibers to provide greater elastically |
|
Osculum Spicules Radial Canal |
O: Exitory channel out of the sponge S: collagen fibers that make sponge skeleton RC: Flagellated chambers after porocytes |
|
Choanocytes Pinacocytes Amebocytes |
C: Create water flow; engulf food particles to pass to amebocytes; become sperm P: Outer layer of cells (not tissue) A: Carry food to cells throughout organism; can be any required cell type |
|
Discoidal Cleavage |
Cleavage planes are at one end of the cell |
|
Fertilization Membrane |
Membrane that forms around the egg to prevent further polyspermy EX: Slow block and fast block |
|
Superficial Cleavage |
Cleavage at cell periphery |
|
Bipinnaria Larva |
Larval stage with morphogenesis and organogenesis |
|
Blastopore |
First opening during gastrulation; the anus |
|
Asconoid Synconoid Leuconoid |
A: No folds, simple, small structure S: Folding of body walls, larger L: folds upon opening, bath sponges, majority are this form of structure |
|
Lacunae (Cartilage) |
Hollow chambers within the matrix; contain chondrocytes |
|
Leukocytes |
Type of white blood cell Function: Defend body from microbes and pathogens EX: Neutrophil-bacterial phagocytosis; Lymphocytes- produce antibodies |
|
Canaliculi |
Tiny channels in lamellae linking osteocytes for communication and nutrient transfer |
|
Regular Dense Connective Tissue |
Description: tightly packed collagen fibers parallel "cables" Location: Tendons, Ligaments Function: Attach bones to muscle and bones to bones |
|
Haversian Canal |
Contains: blood vessels, nerves that exchange nutrients and waste, communicate with osteocytes |
|
Loose Connective Tissue |
Description: Elastic and collagen fibers Location: Between the organs Function: Holding organ tissue together and in place |
|
Smooth Muscle |
Description: lack striation, long spindle-shaped, singular nuclei Location: Bladder, Uterus, Stomach Function: Automatic nerve control; slow, rhyme tic contractions |
|
Fibroblasts |
Cells that secrete collagen and other fibers proteins |
|
Simple Cuboidal Epithelial |
Description: Cube or boxed shaped Location: Kidneys Function: Diffusion and/or absorption across tissue layers |
|
Erythrocytes |
Non-nucleic circular cells used to transport oxygen (O2) and carbon dioxide (CO2); contains packages hemoglobins |
|
Simple Columnar Epithelial |
Description: elongated rectangular shaped cells Function: Diffusion and/or absorption across tissue layers Location: Stomach, Intestines |
|
