animal tissues Flashcards
3 types of epithelial tissues
squamous epithelium, cuboidal epithelium, columnar epithelium
5 types of connective tissues
ligaments, cartilage, bone, blood, adipose
neuron
soma, dendrites, axon, axon terminals
what is the difference between neuron and neuroglia cell
- Neurons are the cells that transmit electrical signals in the nervous system, enabling communication between different parts of the body. Neuroglia (or glial cells) support and protect neurons. They provide structural support, supply nutrients, remove waste, and help maintain the environment around neurons.
neurons
nerve cells
* the structural unit of the nervous system (main building block)
* the “conducting” cells that transmit impulses
neuroglia
nonconductive
* provide a support system for the neurons
where can epithelial tissue be found in the body?
- cover the outside of organs and structures in the body
- lining of your organs (výstelka)
where can columnar epithelia tissue be found
Digestive tract
Respiratory tract
Uterus and fallopian tubes
describe the shape of each tissue
squamous: flat, irregular round shape
cuboidal: cube shaped, central nucleus
columnar: tall, narrow, nucleus toward base
where can ligaments be found in the body?
Knee
Ankle
Shoulder
Blood consists of
plasma
* red blood cells / erythrocytes
* white blood cells / leucocyte
* platelets / thrombocytes
Cartilage is composed of specialized cells
called
chondrocytes
plasma consists of
water, salts
and enzymes
what 2 muscle types appear similiar under the microscope?
cardiac muscle and skeletal muscle.
smooth muscle
- muscle that shows no cross
stripes under microscope - it contracts slowly and
automatically - involuntary muscle
- it constituents the walls of
internal organs and the digestive
system
