16
Q

Hyaline cartilage

A

provides support and flexibility, short and dispersed collagen fibers. Lacunae and chondrocytes

17
Q

Fibrocartilage

A

Shock absorption, tensile strenght. Contains thick bundles of collage fibers dispersed through its matrix (rope like). Meniscus, Intervertebral discs, along stress lines

18
Q

Elastic

A

Flexibility and recoil.. Ex: external ear

19
Q

Bone (SCT)

A

Support, protection, strength

20
Q

Fluid connective tissue

A

Cells suspended in fluid matrix

21
Q

Blood

A

Most abundant: Mostly RBCs with WBCs and platelets

22
Q

Simple vs Stratified

A

Simple is arranged in a single layer, while stratified are arranged in multiple layers

23
Q

Skeletal muscle tissue

A

Voluntary movement, produces heat, protects organs

24
Q

Cardiac muscle

A

Contracts to move blood in the heart

25
Q

Smooth

A

Involuntary movement. In major organs and passageways

26
Q

Origin

A

The end of the mudcle attached to a fixed bone

27
Q

Insertion

A

Movable end of the muscle that attaches to the bone being pulled (mobile attachment)

28
Q

Innervation

A

Nerve providing signal to muscle

29
Q

Vascular

A

Vessels providing blood to the muscle

30
Q

Nervous tissue

A

Mostly cells and little matrix. Conductive and excitable. Neurons and glial cells

31

Neuron

A

Single conductive cell

32
Q

Nerve fiber

A

Axon of neuron

33
