Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Normal Blood (100X)

Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Platelets (Thrombocytes) (1000x) Platelets ● Small (2-4 μm) ● Granular

Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Erythrocytes (RBC’s) Normal Blood (400X) Erythrocytes -Biconcave Discs -Central Pallor

Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Normal Blood Erythrocytes (1000X) Biconcave Discs Central Pallor 7-8 um in diameter

Anatomy & Neurobiology Slide #43: Abnormal Human Blood (Wright-Giemsa) Anemic Blood (100X) Smaller RBC’s Larger Central Pallors Variable Size and Shape

Anatomy & Neurobiology Slide #43: Abnormal Human Blood (Wright-Giemsa) Anemic Blood (400X) Smaller RBC’s Larger Central Pallors Variable Size and Shape

Anatomy & Neurobiology Slide #43: Abnormal Human Blood (Wright-Giemsa) Anemic Blood (1000X) Various Sized RBC’s Larger Central Pallor Variable Size and Shape

Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Granulocytes: Neutrophils (400X) Neutrophils Granular Appearance

Anatomy & Neurobiology Slide #42: Human Blood (Wright-Giemsa) Banded Neutrophils (400X) “Stab Forms” Nucleus Elongated Less Prominent than Segmented Forms
