ANIMALS' SPECIALIZED STRUCTURE
DEVELOPMENT STAGE OF ANIMALS' EMBRYO
Cleavage
- division/segmentation
Morphogenesis
Differentiation
- embryonic tissue
EMBRYONIC TISSUE
Connective
Muscle
Epithelium
Nervous
EPITHELIAL TISSUE
- It lies on basement membrane, cells in this tissue is readily divided to make more cell, cells are firmly attached with each other and it doesn't have vasculature.
CELL SHAPE
-
Squamous
(very thin and much wider)
-
Cuboidal
(cells cube shape, secret and absorb)
-
Columnar
NUMBER OF CELL LAYERS
-Simple
-Pseudo Stratified
-Stratified
CONNECTIVE TISSUE
- It bind and support the tissue and secretes extra cellular matrix.*
TYPES
-
loose connective tissue
(gel like and both elastic and non elastic)
-
dense connective tissue
(nuclei and fiber are arranged in parallel rows)
-adipose
-cartilage
(cells found in lacunae and ground of matrix is gum like)
-bone
(ground of matrix)
-blood
VASCULAR TISSUE
- liquid matrix = plasma (90% water - 10% plasma)
FORMED ELEMENTS
-
Erythroeytes
-
Leukocytes
-
Platelets
MUSCLE TISSUE
- composed of long cells (contraction)
TYPES
-Skeletal
-Smooth
-Cardiac
NERVOUS TISSUE
- sense stimuli and transmit signal in nerve impulse
