the deep layer of dermis consists of:
a.elastic
b.areolar
c.reticular
d.dense regular
e.dense irregular


***the answer can be both reticular and dense irregular connective tissue...which is it? thanks

the answer is
dense irregular
coz dermis consists of two layers
top one is papillary layer
that has more blood vessels,capillaries n sensory neurons which supply surface of skin
n deep layer known as reticular layer of dermis
which consists of meshwork of dense irregular connective tissue

hope it helps

thank you!!...just one more...

A bone lesion with RADIOPAQUE structures radiating from periphery suggests?
a.osteosarcoma
b.osteoblastoma
c.multiple myeloma
d.giant cell tumor
e.osteitis deformans

thanks again!

choice a
Osteosarcoma has radiopaque sunburst appearance makes bone hence radiopacity
Giant cell tumor Radiographically these lesions are characterized by an eccentric osteolytic lesion which extends to subchondral bone producing thinning and bony expansion. Margins may be well or poorly defined but periostitis and sclerosis typically are not present.
Osteoblastoma and multiple myeloma are lucent
The x-ray appearance of Pagetic bone reflects the underlying process. Radiographically, it proceeds through a purely lytic phase, a mixed lytic and blastic phase, and a blastic phase.

here's a mnemonic for radiolucent lesions:
FOGMACHINES

Solitary RadioLucent Bone Lesions

Fibrous Dysplasia
Osteoblastoma
Giant Cell Tumor
Metastasis / Myeloma
Aneurysmal Bone Cyst
Chondroblastoma / Chondromyxoid Fibroma
Hyperparathyroidism (brown tumors) / Hemangioma
Infection
Non-ossifying Fibroma
Eosinophilic Granuloma / Enchondroma
Solitary Bone Cyst
