Types of Animal Cells Flashcards
responsible for the shape of the cell
microtubules in cytoskeleton
are round cells
Spherical Cells
normal rbc count for men
4.7 – 6.1 M per microliter
normal rbc count for women
4.2 – 5.4 M per microliter
deliver oxygen (through the presence of hemoglobin) from the lungs to the brain and other parts
red blood cell
responsible for antibody and immune response
white blood cell
forms blood clotting
platelets
a yellowish liquid in your blood that carries platelets, red blood cells and white blood cells around the body
plasma
constitutes 55% of the blood
plasma
constitutes 44% of the blood
red blood cell
enucleated (no nucleus) with an average diameter of 7 micrometers
red blood cell
constitutes 1% of the blood
white blood cell & platelets
another term for rbc
erythrocytes
cells with numerous protoplasmic processes
Stellate Cells
Where are stellate cells found?
- Fibroblasts
- Resting osteocytes
- Reticulocytes
- Many glial cells
a type of cell that synthesizes the extracellular matrix and collagen
Fibroblasts
the structural framework (stroma) for animal tissues
collagen
plays a critical role in wound healing
Fibroblasts
the most abundant cell found in compact bone
Osteocytes
contain a nucleus and a thin ring of cytoplasm
Osteocytes
immature red blood cells
Reticulocytes
composing about 1% of the red cells in the human body
Reticulocytes
process of maturation of reticulocytes
- develop and mature in the red bone marrow
- circulate for about day in the blood stream
supporting cells of neurons
Glial Cells
Functions of Glial Cells
- To surround neurons and hold them in place
- To supply nutrients and oxygen to neurons
- To insulate neuron from one another
- To clean up (destroy and remove the carcasses of dead neurons)
Notable Glial Cells in the CNS
- oligodendrocytes
- astrocytes
- microglia
- ependymal cells
Notable Glial Cells in the PNS
- schwann cells
- satellite cells
- enteric cells
flat and polygonal cells
squamous cells
the most common cells of connective tissue in animals
Fibroblasts
squamous cells found in the mucus lining
- oral cavity (mouth)
- cornea (eye)
- vagina
box-like with the nucleus placed at the center
Cuboidal Cells
examples of cuboidal cells
- kidney tubules
- Ducts
functions of cuboidal cells
- resorption
- secretion
- formation of urine
cells where each nucleus is located at the base of the cell
Columnar Cells
found in the respiratory, digestive mucus linings and trachea
Columnar Cells
cells with an oval nucleus
Oval Cells
taper or narrow down at both ends and the nucleus is located at the center
Fusiform Cells
Where is fusiform cells found?
Smooth Muscles
are like the striated skeletal muscles where the nucleus is peripherally located
Cylindrical Cells
have numerous surfaces and sides
Polyhedral Cells
the nucleus of each cell is immediately surrounded by a perinuclear sarcoplasm that is devoid of striations
Branch Cylindrical Cells
situated near or occurring around the nucleus
perinuclear
