A
DENSE REGULAR ELASTIC CONNECTIVE TISSUE
19
Q
SKELETAL CONNECTIVE TISSUE
A
HYALINE CARTILAGE
FIBROCARTILAGE
ELASTIC CARTILAGE
BONES
20
Q
SKELETAL CONNECTIVE TISSUE
- Collagen fibers are small and evenly dispersed in the matrix, making the matrix appear transparent; the chondrocytes are found in spaces, or lacunae, within the firm but flexible matrix
A
HYALINE CARTILAGE
21
Q
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Allows growth of long bones; provides rigidity with some flexibility in the trachea, bronchi, ribs, and nose; forms strong, smooth, yet somewhat flexible articulating surfaces, forms the embryonic skeleton
A
HYALINE CARTILAGE
22
Q
SKELETAL CONNECTIVE TISSUE
LOCATION
- Growing long bones, cartilage rings of the respiratory system, costal cartilage of ribs, nasal cartilages, articulating surface of bones, and the embryonic skeleton
A
HYALINE CARTILAGE
23
Q
SKELETAL CONNECTIVE TISSUE
- Collagen fibers similar to those in hyaline cartilage; the fibers are more numerous than in other cartilages and are arranged in thick bundles
A
FIBROCARTILAGE
24
Q
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Somewhat flexible and capable of withstanding considerable pressure; connects structures subjected to great pressure
A
FIBROCARTILAGE
25
SKELETAL CONNECTIVE TISSUE
LOCATION
- Intervertebral disks, pubic symphysis. and articular disks (eg. knees and temporomandibular (jaw) joints)
FIBROCARTILAGE
26
SKELETAL CONNECTIVE TISSUE
- Similar to hyaline cartilage, but matrix also contains elastin fibers
ELASTIC CARTILAGE
27
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Provides rigidity with even more flexibility than hyaline cartilage because elastic fibers return to their original shape after being stretched
ELASTIC CARTILAGE
28
SKELETAL CONNECTIVE TISSUE
LOCATION
- External ears, epiglottis, and auditory tubes
ELASTIC CARTILAGE
29
SKELETAL CONNECTIVE TISSUE

SUPPORTING CONNECTIVE TISSUE: BONE
30
SKELETAL CONNECTIVE TISSUE
FUNCTION
- Provides great strength and support and protects internal organs, such as the brain; bone also provides attachment sites for muscles and ligaments; the joints of bones allow movements

CARDIAC MUSCLE
39
MUSCULAR TISSUE
LOCATION
- In the heart
CARDIAC MUSCLE
40

SMOOTH MUSCLE
41
MUSCULAR TISSUE
FUNCTION
- Regulates the size of organs, forces fluid through tubes, controls the amount of light entering the eye and produces ‘’goose bumps” in the skin, under involuntary (unconscious) control
SMOOTH MUSCLE
42
MUSCULAR TISSUE
LOCATION
- In hollow organs, such as the stomach and intestines; skin and eyes.
SMOOTH MUSCLE
43
NERVOUS TISSUE
- A neurons consists of dendrites, a cell body, and a long axon; neurolgia, support cells, surround the neurons
NERVOUS TISSUE: NEURONS
