Animal Tissues

Epithelial tissue

• Simple (single layer) cuboidal (cube shape)

• Simple columnar (single layer of column shape)

Nervous Tissue

• Neuron (nerve cell): Cell body, dendrite, axon. Glial cells support the neuron

Neurotransmitter crosses synapse

Schwann cells make

up the myelin sheath. Impulse

jumps from node to node

3 types of muscle tissue:

skeletal, smooth, cardiac

• Striations Intercalated discs

• Loose connective tissue (under skin and epithelial tissue)

Bone• Haversian canal

with blood vessel and nerve

• Lacuna openings with osteocytes in them

• Calcium carbonate matrix

Blood:Erythrocytes, red blood

cells

• Hemoglobin carries oxygen• No nucleus• Made in bone marrow

Leukocytes: White blood cells

Thrombocytes: platelets

• Platelets adhering to damaged vessel

Blood composition

• RBC (hematocrit) 40%

• WBC 1%• Platelets 1%• Plasma 58%

Tendon: bone to muscleMore flexible and thicker

Ligament: bone to boneNot as flexible or thick
