1.1.3 Held Together by a Thread Flashcards
cell
smallest unit of life
tissue
an integrated group of cells with a common function and/or structure
organs
a collection of tissues in an organism that performs a specific function, such as the heart, brain, skin, and liver
organ systems
a group of organs that work together to perform one or more function
histology
the study of the microscopic anatomy of tissues, also known as microanatomy.
physiology
the way in which a living organism or bodily part function
location of nervous tissue
nerves, the spinal cord, and the brain
function of nervous tissue
to receive, interpret, and respond to signals
location of epithelial tissue
outer surfaces of all organs and blood vessels, in the mouth, and on the surfaces of humans (lining)
functions of epithelial tissue
works to absorb, secrete, protect, and sense for us (lining)
location of muscle tissue
makes up the muscles in the body
three types of muscle tissue
skeletal, smooth, and cardiac
location of skeletal muscle tissue
attached to bones
location of smooth muscle tissue
walls of internal organs
location of cardiac muscle tissue
in the walls of the heart
function of muscle tissue
provides the ability to contract and move
location of connective tissue
is attached to and in between other tissues
Function of connective tissue
Works to hold organs in place, attach muscle to bones, link bones with joints, and enable other tissues to stretch.
what is a histologist
a medical scientist who prepares, examines and tests samples and specimens from humans, animals and plants. The work they do can help diagnose diseases or discover abnormalities within samples.
What is adipose
Also known as fat, a type of connective tissue filled with lipid cells.
What is blood
Fluid (plasma) that circulates the body that contains rbc, wbc, and platels.
What is the function of blood
It transports nutrients, transports oxygen and carbon dioxide, transports hormones, regulates body pH and temperature, immune defense.
What is cartilage function
Cartilage has many functions, including the ability to resist compressive forces, enhance bone resilience, and provide support on bony areas where there is a need for flexibility
Function of tendon
A tendon is a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Function of ligament
Very small band of flexible and hard connective tissue (very fibrous), Connects two bones or cartilages. Also holds together a joint.
What is a nerve
A bundle of fibers that sends impulses of sensation to the brain or spinal cord, and then sends to and from the muscles and organs
function of orbicularis oculi
surrounding the eyeball. Allows you to close your eyes and squint
function of orbicularis oris
lips. allows you to do anything with your lips (eating, talking, spitting, drinking, etc.)
function of temporalis
side of the head, superior to ear. Allows you to move lower jaw.
How does the distribution of tissues contribute to our appearance and to our identity?
Bone tissue can shape our skeleton, muscle tissue can give us a more or less full figure, and fat tissue can determine the shape of cheeks and eyes. Think about the action of the muscles you have built on your maniken.
