|
Acne
|
Inflammation of the sebaceous glands, especially beginning at puberty; Follicle becomes blocked with keratinocytes and sebum and develops into a whitehead (comedo) composed of these and bacteria
|
|
|
Nails are derivatives of
|
stratum Corneum
|
|
|
Vitamin D synthesis
|
Epidermal keratinocytes use UV rays form sun
|
|
|
Jaundice
|
High levels of bilirubin (a RBC breakdown fragment normally disposed of by the liver)
|
|
|
Hypodermis
|
- Subcutaneous tissue
- A lot of other loose connective tissues & More adipose and areolar tissues! - Subcutaneous fat deposition: Shown in different parts depending on male/female - Energy reservoir - Thermal insulation |
|
|
Dermis (two layers)
|
Reticular layer and papillary layer
|
|
|
Reticular Layer
|
•Collagen here forms thicker bundles with less room for ground substance, and often small clusters of adipocytes
•Full of fibers – reticular fibers •Dense connective tissue because it is full of stuff •Mostly obesity, but also pregnancy can tear the collagen fibers here and product striae (stretch marks!) |
|
|
Papillary Layer
|
Thin zone of areolar tissue in and near dermal papillae and Rich in small blood vessels
|
|
|
Stratum Corneum
|
•Up to 30 layers of dead, scaly, keratinized cells that form a durable surface later.
•Releasing keratin which is an important barrier for waterproofing your skin |
|
|
Stratum Lucidum
|
•The keratinocytes are densely packed with a clear protein, eleidin
|

|
|
Stratum Basale
|
He didn’t mention in lecture but basically single layer of cuboidal to low columnar stem cells and keratinocytes resting on the basement membrane.
Scattered among are melanocytes and tactile cells. As its stem cells dive, they give rise to keratinocytes that migrate toward skin surface and replace lost epidermal cells. |
|
|
Dendritic Cells
|
types of macrophages and Signal that immune response
|
|
|
The elbow
|
Arthroscopy. & Saline blows up and keeps the joint open and minimizes the joint so it relaxes I believe
|
|
|
The ligaments
|
- ACL = soccer
- The Tibeal collateral ligament - Healing is going to be really slow - Cartilage = no blood flow - Very low blood supply for ligaments and tendons - Graft from patellar ligament or hamstring tendon Blood vessels infuse, get regrowth. 6-12 months. |
|
|
Elastic Filaments
|
Made of huge springy protein, titin (connectin)
|
|
|
Epidermis
|
stratified squamous EPITHELIAL tissue!
|
|
|
Dermis
|
fibrous connective, muscle, and nervous tissue (also has lots of collagen! And supplied with blood vessels, sweat glands, sebaceous glands, and nerve endings, hair follicles, and nail roots!)
|
|
|
Hypodermis
|
connective tissue (he says). Book says areolar or adipose tissue between skin and muscle
|
|
|
Muscle Dystrophy
|
- Collective term for several hereditary diseases in which muscles degenerate, weaken, and are gradually replaced by fat and fibrous scar tissue. Most common form of the disease is Duchenne muscular dystrophy (DMD), a sex-linked recessive trait affecting about 1 out of every 3,500 live-born boys. Hips legs abdominal, spinal, respiratory, and cardiac muscles. Seldom live past 20. Gene mutation for dystrophin.
- Oxygen now being delivered and supported by cardiopulmonary function - After you have been exercising for longer than 10 minutes, 90% of ATP comes from anaerobic respiration |
|
|
Fibromyalgia
|
i. Diffuse, chronic muscular pain and tenderness, often associated with sleep disturbances and fatigue; often misdiagnosed as chronic fatigue syndrome. Can be caused by various infectious diseases, physical or emotional trauma, or medications. Most common in women 30 to 50 years old.
|
|
|
Delayed-Onset Muscle Soreness
|
i. Associated with microtrauma to the muscles, with disrupted Z discs, myofibrils, and plasma membranes, and with elevated levels of myoglobin, creatine kinase, and lactate dehydrogenase in the blood.
|
|
|
Outer fibrous capsule of synovial joint
|
continuous with periosteum of adjoining bones, and an inner, cellular synovial membrane
|
|
|
Joint capsule of synovial joint
|
encloses cavity and retains fluid
|
|
|
Accessories of synovial joints
|
The tendons = Composition: collagen and other connective tissues
Ligaments = Also made up of collage and other connective tissues The tendon sheets are the versa! |
