Histology Flashcards
Epithelia are classified on the basis of
number of cell layers and shape of cells at the apical surface
They are made up of compactly arranged cells.
Epithelial Tissues
During an injury, nasal septum gets damaged and for its recovery which cartilage is referred?
hyaline cartilage
Which type of epithelial cell is best adapted to aid diffusion?
Simple
This kind of tissue functions for excretion (eg. glands).
Glandular
This kind of tissue functions as the transporting medium in the body.
Connective tissue
A connective tissue with fluid matrix
Blood
It binds one part of the body to another.
Connective tissue
The cells that consist this tissue is made up of myofibrils.
Muscle tissue
Which of the following is true about pseudostratified ciliated columnar epithelium?
propels mucus or reproductive cells by ciliary action
It enables the organism to respond to the environment.
Nervous tissue
Which is responsible for eliciting antibody response?
Lymphocytes
In which of these tissues is Haversian system found?
Bone
The functional unit of a nervous tissue
Neuron
Type of neurons that act as effectors
Motor neurons
Specific type of connective tissue found on tendons and ligaments.
Dense
It fills spaces between organs.
Connective tissue
It is made up of fat cells or adipose
connective tissue
Which among the following is NOT the characteristic feature of smooth muscle fibers?
present in internal organs
cylindrical in shape
involuntary in nature
organized into sheets of muscle
cylindrical in shape
This tissue is made up of intracellular substances.
Connective tissue
Muscle that are striated, with one nucleus per cell, and contracts involuntary.
Cardiac muscle
Muscle found in walls of intestinal organs, bladder, various ducts, arteries and veins.
Smooth muscle
Muscle that can be controlled by the central nervous system
Skeletal muscle
Another term for cardiac muscle
Intermediate muscle
produces fibers
Osteoblast
cell that sits in a lacuna
Osteocyte
cell involved in bone resorption
Osteoclast
The functional unit of a bone
Osteon
connective tissue (CT) found on tendons and ligaments
Dense ct
connective tissue that forms the framework of liver, lymph nodes and spleen
Reticular CT
connective tissue found in lung tissue and large arteries
Elastic ct
connective tissue usually found under epithelia
Loose ct
Blood cell that carries oxygen
erythrocytes
blood cell that produces antibodies
Lymphocytes
responsible for blood clotting
Thrombocytes
eosinophils, basophils, neutrophils
Granulocytes
epithelial tissue in the lining of trachea
Ciliated pseudostratified columnar
epithelial tissue in the lining of kidney tubules
Simple cuboidal
epithelial tissue in the lining of intestine
Simple columnar
epithelial tissue in the lining of blood vessels
Simple squamous
Adipocytes
Ct
Glial cells
Nervous tissue
Keratinocytes
Epithelial Tissue
Myofibril
Muscle tissue
functional unit of the myofibril
Sarcomere
the thick myofilament in a muscle
Myosin
layer of connective tissue that separates the muscle tissue into smallest sections
Endomysium
Striations in muscles are due to alternating bands of thick and thin ____
Myofilaments
Found in brain & spinal cord
Responsible for reacting to changes
Are always sensory neurons
Most common type of neuron
conducts impulses away from the cell body
Axon
conducts impulses toward the cell body
Dendrites
insulates axon and facilitates conduction of impulse faster
Myelin
protect and support neurons
Nueroglia
All blood cells are nucleated.
False
Epithelial layer is a permeable layer.
True
Cardiac muscle is intermediate between skeletal and smooth muscles.
True
Connective tissue consists of long cells which contract in response to nerve signals.
False
Epithelial cells are separated from one another by large amounts of extracellular matrix.
False
Epithelial tissue stores fat for insulation and fuel.
False
Glands are made up of cells derived from connective tissue.
False
Epithelial layer does not allow regulation of materials between body and external environment.
False
Connective tissues are similar to epithelial tissues with little or no intercellular space between them
False
Organs are formed by an orderly combination of several types of tissues.
True
