Lab 16 Outline: Vertebrate Tissue Flashcards
1
Q
epithelial tissue
A
covering and lining of the organs
protection, exchange, and production of materials
2
Q
simple
A
one layer
3
Q
stratified
A
two or more layers
4
Q
squamous
A
thin flat cells
5
Q
simple squamous
A
exchange of materials
ex: capillaries and alveoli
6
Q
simple stratified
A
protection
ex: oral mucosa, and epidermis
7
Q
cubodial
A
cube or pyramid shape
lines ducts and secretory portions of glands( pancreas and thyroid)
8
Q
columnar
A
- tall and narrow
- secretion, absorption, and transport of nutrients
ex: stomach and small intestine
9
Q
Muscle Tissue
A
movement of body parts
10
Q
cardiac muscle
A
cross striations branched few nuclei involuntary walls of heart
11
Q
skeletal muscle
A
cross striations unbranched hundreds of nuclei under voluntary control 40% of body weight
12
Q
smooth muscle
A
no cross striations spindle shaped cells large nuclei involuntary long, sustained contraction
ex: walls of blood vessels and intestines
13
Q
connective tissues
A
- extracellular matrix; up to 90% of volume, varying consistencies
- few scattered cells
- adhesion, shaping, structural strength and transport
14
Q
Bone
A
ECM: collagen fibers and CaPO4 lacunae with osteocytes canaliculi lamellae central blood vessles heavy and hard for protection and support
15
Q
Hyaline Cartilage
A
- ECM; firm with cartilage
- little vascular supply causing nutrients to diffuse through the matrix
- lightweight and flexible
- support and protection ( larynx, trachea, and bone articulations)
- most bones begin as cartilage
