Exam 2 Review
Structure and Composition of Muscle Tissue
Epithelium Thinlayer of tissue that covers all free surfaces of the body
Nervous Tissue Made of neuron andglial cells end functions to transmit electrical
impulses thru body
Neuron nerve cell
Glialcell support cell that help insulate and support the nerve cell
Connective Tissue provides the structural framework of an animal
Epimysium surrounds entire muscle E entire
Terimysium surrounds the muscle bundle where marbling is located P partial
Endomysium surrounds the myofiber muscle cell Endo internal

Adipose Stores
energy cushions organs insulates body
type of loose connective tissue most common

storage for Ca P Mg Na
Cartilage firm elastic connective tissue Found atends of long bones at joint
Collagen Mostabundant protein found in animals 20 30 of total protein
Located in skin and extracellular space in the body
