What is connective tissue?

Tissue that connects or binds structures together, support the body, and aid in bodily maintenance.

What are the three types of connective tissue?

Loose
Dense
Specialized

What are the two types of loose connective tissue?

Areolar
Adipose

Areolar tissue

found just below the skin
forms the bed for skin and mucous membranes

Adipose tissue

similar to areaolar tissue but has a high concentration of fat cells

What are the different types of dense connective tissue?

Tendons
Ligaments
Fascia
Reticular

Tendons can always be associated with a ______________.

muscle

What are the physical characteristics of tendons?

tough, nonelastic cords

Tendons attach...

muscle to bone, cartilage, or one another.

Aponeuroses (a type of tendon) are...

broad sheets of tendonous expansions serving as a covering for muscle.

What are the physical characterists of ligaments?

elastic fibers

Ligaments join...

bone to bone, bone to cartilage, and cartilage to cartilage.

Fascia denotes all of the ...

dense fibrous connective tissues not otherwise designated as tendons, aponeuroses, or ligaments

Fascia is usually found in the form of ______________.

membranous sheets

Reticular tissue is a very delicate matrix of cells which have processes that...

extend in all directions to join neighboring cells

Reticular tissue forms a supporting framework for...

the lymph nodes and liver.

What are the two kinds of specialized connective tissue?

Cartilage and bone

What are the three types of cartilage?

Hyaline
Elastic
Fibrocartilage

Hyaline cartilage

covers the articular surfaces of joints and forms the framework for the lower respiratory tracts.

Where is elastic cartilage found?

in the ear
external auditory meatus
epiglottis
auditory tube
some small cartilage of the larynx

How many bones are in the human skeleton?

206 bones

The bones in the human skeleton are divided into an ______________ and ______________ skeleton.

axial and appendicular

Bones are classified as...

long, short, irregular, or accessory

What are the characteristics of bone?

dense or compact bone
spongy of cancellous bone

How do bones differ?

only in the degree of porosity and in architecture.

What are joints?

the connections between bones that create movement

What are the three types of joints?

Synarthroidal (fibrous, immovable) joints
Amphiarthroidal
Diarthroidal (Ssynovial, movable) joints

Types of diathroidal joints

gliding
hinge
pivot
condyloid
saddle
ball and socket

What is the movement of a diathroidal joint?

widely varying degrees and directions of free movement

What is the movement of a amphiarthroidal joint?

permits a certain amount of movement or give as contiguous bone edges are united by interposing cartilage

What is the movement of a synarthoidal joint?

No movement in these joints.
The connected pair or group acts as a single bone
Example: the skull

In synarthroidal joints, bones are almost in direct contact with one another and are joined together by a thin thin line of ______________.

connective tissue

What are the places on the skull where the bone meet called?

sutures
