Adduction
What are the classifications of connective tissue?
1. Connective Tissue Proper
2. Supporting Connective Tissue
3. Fluid Connective Tissue
What is the deepest epidermis layer?
What cells are found there?
Stratum basale
Keratinocytes
Melanocytes
Tactile cells
projects of the dermis that intertwine with the epidermis and contain blood vessels that nourish the epidermis.
Also, contain tactile receptors, which monitor touch
In the papillary layer of the dermis
Dermal Papillae
What is the first step of bone fracture repair?
a fracture hematoma (blood clot) forms
What type of joint is being described?
No joint cavity and held together by dense regular Connective Tissue
Fibrous joint
What type of connective tissue is being described?
• Tightly packed, parallel collagen fibers
• Resemble stacked lasagna noodles
• Stress typically applied in a single direction
• Takes a long time to heal
Function: attaches bone to bone, resists stress in one direction
Location: tendons and ligaments, Few blood vessels
Dense Regular Connective Tissue
Yellow orange pigment acquired from eating certain veggies and is converted to Vitamin A.
Carotene
What angular motion is this?
the trunk of the body laterally moves in a coronal plane away from the body
Lateral flexion
What zone is being desribed?
walls of lacunae disintegrate, and space is invaded by blood vessels and osteoprogenitor cells.
A new matrix of bone is deposited
Bone with a rounded surface that fits into a ring formed by a ligament and another bone.
They are freely moveable (diarthrosis)
Ex: Atlantoaxial joint
Pivot joint
makes up a solid ECM that provides support to the body by providing levers for movement
Provides support to soft tissues and protects vital body organs
Bone
modified apocrine glands that secrete cerumen (waterproof ear wax).
Traps foreign particles and keeps objects from
reaching the ear drum.
Ceruminous glands
What do the ABCDE's stand for in regards to skin cancer
A: Asymmetry
B: Border
C: Color
D: Diameter
E:Evolving
A sheet of connective tissue that helps maintain shape
Perichondrium
What cartilaginous joint is being described?
articulation where bones are joined by hyaline cartilage
Example: epiphyseal growing plate
Function: synarthrosis (immobile)
Synchondroses
What epithelial type is being described?
Two or more layers of cells
Superficial cells cuboidal in shape
Forms tubes and coverings
Function: Protection and secretion
Location: Forms walls of ducts in most exocrine
glands, sweat glands, parts of male urethra, periphery of ovarian follicles
Stratified Cuboidal Epithelium
What are the functions of hair?
protection
facial expression
heat retention
sensory reception
visual identification
chemical signal dispersal
What process is being explained?
Hint: this is the first steps of the process.
Cartilage calcifies and chondrocytes die, osteoblast forms stem cells in the periosteum, osteoblast secrete osteoid, and a periosteal bone color forms around diaphysis.
Endochondral Ossification Process
Anchors bone to bone
Ligaments
What movement of synovial joints is this?
A movement where two opposing surfaces slide back and forth or side to side in respect to each other.
Gliding motion
