|
Why is skin considered an organ? |
Because it has two or more tissue types. |
|
|
Functions of Integumentary System? |
Protection from abrasions, chemicals, U-V Light, desiccation, help control body temperature, recievie stimuli, excrete wastes, synthesize vitamin D. |
|
|
Dermis |
Consists of Papillary Layer and Reticular Layer, reticular layer is fibrous papilary layers have papillae which provide support for epidermal ridges, connect epidermis to dermis and supply cells with nutrients. |
|
|
Nerve Endings |
Free Nerve Endings: Pain Root Hair Plexus: Responds to Movement Meissners Corpuscles: Respond to Touch Pacinian Corpuscles: Respond to Pressure |
|
|
Stratum Corneum |
Outermost cornified layer consisting of keratinized dead stratified squamous epithileal cells. |
|
|
Stratum Granulosum |
Accumulate Keratin Protein Granules. |
|
|
Stratum Basale |
deepest epidermal layer where cell reproduction occurs. |
|
|
Epidermal Layer |
Provides outer protective layer. Has no capillaries or veins and skin is dead. |
|
|
Glands |
Sweat Glands use merocrine secreation process and are called psuedorifirous glands. Oil glands are sabesious glands. |
|
|
Intermembranous Bone Formation |
Process by which bone is formed within fibrous connective tissue. Compact bone is formed over the top of spongey bone. |
|
|
Endochondral bone formation |
Epithelial plate is ossified in fetal skeleton. |
|
|
Calcium Homeostasis |
Calcium blood levels are maintained by hormones and calcium is neccesary for maintaing cell membrane permeability and muscle function. Negative Feedback: Calcitonin is secreated from the thyroid gland at this causes calcium minerals to deposit in bone. Absorbtion of calcium depends on proteins inside the walls of the small intestine. Positive Feedback: PCH from parathyroid. |
|
|
Functions of Skeletal System |
System of levers, supports body tissues, produces red blood cells and protects organs. |
|
|
Compact Bone |
Charcterized by Haversian systems. Provides surface bone for the epiphyses and for structural support in the thick bone of the diaphysis. |
|
|
Spongy (Cancellous) Bone |
Consists of bony trabeculae. Provides support for compact bones and fills space in the interior of bone, spaces between trabeculae are filled with yellow or red bone marrow. |
|
|
Ethmoid Bone |
Contains ethmoidal sinus and nasal conchae or turbinate bones which have good blood circulation. |
|
|
Differences Between Male & Female Pelvis |
Male; Heavy, compact, narrow across bowl at iliac spine, heart shaped true pelvis, acute (90 or less) pubic arch angle.
Female: Light, wide, wide across pelvic bowl at iliac spine. Round true pelvis obtuse pubic arch angle. |
|
|
Three types of Joints |
Fibrous- Articulating bones that are held tight together with fibrous connective tissues. Cartilangeous- Articulating bones connected by flexible cartilidge. Synovial- Joint is freely moveable |
|
|
Types of Fibrous Joints |
Sutures of the skull, syndemosis (layer between bones), Gomphosis (tooth attachment). |
|
|
Types of Cartilaginous Joints |
Synchondrosis- costal cartilidge Symphysis- bones are connected by broad, flat disc of fibrocartilidge. |
