Answer 5

subcutaneous layer under the skin, surrounds organs.

chaotic, spider web like

Question 6

reticular connective tissue

Answer 6

forms stroma of lymph nodes

grapes on a vine

Question 7

adipose connective tissue

Answer 7

subcutaneous layer of the skin, surrounds organs.

hexagon (6 ish sides) shape

Question 8

Dense connective tissues

Answer 8

dense regular connective tissue
elastic connective tissue
Dense irregular connective tissue

Question 9

Dense Regular connective Tissue

Answer 9

Forms Tendons (muscle to bone) 
*parallel pattern (waves)

Question 10

Elastic connective tissue:

Answer 10

Trachea

Dark squiggly lines

Question 11

Dense Irregular connective tissue:

Answer 11

Dermis,

*no pattern, Bacon like :) *

Question 12

Supporting connective tissue:

Answer 12

Bone or Osseous Tissue: Compact bone

Cartilage Tissues: Hyaline cartilage, Fibrocartilage, Elastic Cartilage.

Question 13

Bone or Osseous Tissue

Answer 13

Compact Bone

Question 14

Compact Bone

Answer 14

exterior of bones of the body
*Black and White: Osteon (tree ring/bullseye)

Outer shell of bone

Question 15

Cartilage Tissues:

Answer 15

Hyaline cartilage, fibrocartilage, elastic cartilage.

Question 16

Hyaline Cartilage:

Answer 16

Most of the nose, Most abundant,

• Glassy appearance
• Smooth + lacunae = hyaline cartilage

Question 17

Fibrocartilage:

Answer 17

Meniscus of knee

• sparse linear lucunae
• stains a bluish color.

Question 18

Elastic cartilage

Answer 18

external ear

• dense lucunae
• Lucunae + rough = elastic cartilage

Question 19

Muscle tissues

Answer 19

Smooth, skeletal, cardiac

Question 20

smooth muscle:

Answer 20

Wall of stomach,
*no striations- “spindle like”

Involuntary movements (dialating eyes, blood vessels) one central nucleus

Question 21

Skeletal muscle:

Answer 21

attaches to bone

• long and unbranched
• multiple nuclei with straitions

Voluntary movement, cells as long as the muscle
Nuclei in cell periphery

Question 22

Cardiac muscle

Answer 22

Heart wall

• short and branched(splits)
• *striations and intercalated discs (darker lines)

Shorter fibers than skeletal.
One or two central nuclei

Question 23

Nervous Tissue:

Answer 23

Nervous Tissue: located in brain and spinal cord.
(neuron, soma, axon, dendrites) controls communication between cells.

Neurons(in through dendrites, out through axon) supporting glial cells

Question 24

Body membranes:

Answer 24

Line major cavities of internal (visceral) and external(parietal) surfaces.

Question 25

Internal membranes:

Answer 25

Mucous- lines passageways that open to external environment ex: digestive, respiratory, urinary, reproductive

Serous- simple squamous epithelium produces thin watery fluid to lubricate ex: pericardium, peritoneum, pleura

Others-largest membranes is the cutaneous membrane (skin) synovial membranes line skeletal joints,
