Ermelat Flashcards
Distinctive characteristic of smooth muscles
Lack of striations
Functions in limiting hemorrhage to the endothelial lining of the blood vessel in case of injury.
Platelets
Individual muscle cells cannot contract independently.
Unitary smooth muscle and Single unit smooth muscle cell
Arrange the white blood cells according to number from highest to lowest in an average normal person.
I. Neutrophil
II. Eosinophil
III. Basophil
IV. Lymphocytes
V. Monocytes
I. Neutrophil – 60%-70%
II. Eosinophil – 4%
III. Basophil – 1%
IV. Lymphocytes – 20%-25%
V. Monocytes – 3%-8%
Neutrophil, Lymphocytes, Monocytes, Eosinophil, Basophil
Composed of loose arrangement of fibers and dispersed cells embedded in a gel-like ground substance.
Loose connective tissue
Nonstriated, fusiform in shape muscle cells.
Smooth
Specific granules of this WBC stain dark blue to black and the constitute less than 1% of the WBC count
Basophil
Statement I: Cardiac muscle is striated type of muscle.
Statement II: Cardiac muscles contain more than 2 nucleus and found centrally.
Both statements are true
This cycle lasts from a few hours to several days. Cell growth and protein synthesis occur, restoring daughter cells to normal volume and size.
G1 phase
Statement I: Fetal hemoglobin consists of 2 alpha globin chains and 2 gamma globin chains.
Statement II: Oxygen molecule binds to the iron found on the heme group of the hemoglobin.
Both statements are true
Complex steplike junctions forming end to end attachments between adjacent cardiac muscle cells.
Intercalated discs
Kill some foreign and virally altered cells without the influence of thymus.
B cells
What type of connective tissue is adventitia of blood vessels.
Dense regular elastic connective tissue
Statement I: Dense irregular connective tissue is mostly coarse collagen fibers interwoven into meshwork.
Statement II: Fibroblasts are the most abundant cells found in dense irregular connective tissues
Both statements are true
Which band/lines in cross striations of myofibrils describes isotropic, light stained and contains thin filaments only.
I-bands
On thin filaments, this troponin has 4 binding site for calcium.
TnC
Neutrophilic granules that contain various enzymes and pharmacological agents in performing antimicrobial function
Specific granules
Rigor mortis:
A. Inhibition of acetylcholine release at myoneural junction
B. Myosin remains bound to actin thus muscles remain contracted
C. Antibodies block acetylcholine receptors
D. Actin and myosin filaments enlarged
B. Myosin remains bound to actin thus muscles remain contracted
Aids in maintaining the structural and functional integrity of the cell. Also functions as semi-permeable membrane between cytoplasm and external environment
Plasma membrane
It is composed of coarse collagen bundles densely packed and oriented in parallel cylinders.
Dense regular collagenous connective tissue
What blood tube will you use to have a serum from blood sample.
SST – serum separating tube
Helps eliminate antigen-antibody complexes and destroy parasitic worms.
Eosinophil
Wharton’s jelly is what type of connective tissue?
Mucous connective tissue
TRUE OR FALSE. Tendons, ligaments, and aponeurosis are example of a dense regular collagenous connective tissue.
TRUE
Arise from bone marrow stem cells and function in mediating the inflammatory process and immediate hypersensitivity reactions
Mast cells
Statement I: Inclusions are lifeless accumulations of material inside the cell.
Statement II: Microtubules is one of the examples under inclusions.
First stament is true, second is false. Microtubules is under cytoskeleton.
Can transmit a wave of excitation throughout the cell from the point of stimulus and highly developed in nerve cells.
Conductivity
Epithelium where single layer of cells resemble rectangle, height is wide than width.
Simple columnar
Example of the simple columnar, except:
A. Small bronchi
B. Gall bladder
C. Salivary glands
D. Digestive tract
C. Salivary glands
Largest of neurological cells
Astrocyte
Produced by oligodendrocytes and Schwann Cells which envelope individual axons.
Myelin sheath
Epithelium composed of dome-shaped cells on the superficial layer with multiple columnar and cuboidal cells.
Transitional epithelium
Example of Transitional Epithelium
A. Stomach
B. Lens of eye
C. Ureter
D. Tymparic membrane
C. Ureter
TRUE OR FALSE. Axons send impulses toward the soma to the axon terminals
FALSE. Axon send impulses AWAY from the soma to the axon terminal
Mechanism of secretion where the entire secretory cell along with its contents are released.
Holocrine
Example of exocrine gland
Lactating Mammary Gland
Covering each bundle of nerve fiber.
Perinerium
Clear fluid that circulates through the ventricles, subarachnoid space, and central canal
Cerebrospinal fluid
Example of holocrine gland
Sebaceous gland
Receive stimuli from axons.
Dendrites
