What is the function and location of Simple Squamous?
What is the function and location of Areolar?
Location: under Epithelial Tissue & wraps around organs
Function: cushion, protect, & anchor other tissue
What are the functions of the Integumentary System?
What are the functions of the skeletal system?
What are the other two types of tissue (besides epithelial and connective)? Describe them.
Nervous --> allows communication
Muscle
- Cardiac: heart tissue, histology = striated disks
- Smooth: internal organs
- Skeletal: f(x) = locomotion, histology = striated
What is the function and location of Simple Columnar?
What is the function and location of Adipose?
Location: hypodermis, breasts, abdomen, & surrounding organs (such as the kidneys)
Function: insulation protection, & fuel
List all the layers of the integumentary system from most superficial to deep.
Stratum Corneum
Stratum Lucidum (in thick skin)
Stratum Granulosum
Stratum Spinosum
Stratum Basale
Dermis - Papillary
Dermis - Reticular
Hypodermis
List and describe all types of skeletal system cells.
- Osteogenic cell: Stem Cell
- Osteoblast: Matrix-synthesizing cell responsible for bone growth (bone building)
- Osteoclast: Bone-resorbing cell (bone breaking)
- Osteocyte: Mature bone cell that maintains the bone matrix
What are the 3 types of arthritis?
Osteoarthritis: Inflammation of one or more joints. It is the most common form of arthritis that affects joints in the hand, spine, knees and hips.
Rheumatoid Arthritis: autoimmune and inflammatory disease, results in painful joints, swelling and stiffness in the joints.
Gouty Arthritis: A type of arthritis that causes inflammation of joints due to excess uric acid. Usually in the big toe.
What is the function and location of Pseudostratified Columnar?
What is the function and location of Reticular?
Location: lymph organs (such as the spleen & lymph nodes)
Function: soft skeleton for WBCs to perch on as they wait for pathogens in lymph organs.
What are the two types of sweat glands and what is different about them?
Eccrine
Apocrine
What is an osteon? List and describe all the parts in an osteon.
Osteon: Structural Unit; group of hollow tubes of bone matrix
Lamellae: weight-bearing column-like tubes of extracellular matrix that act like the rings of a tree. They have collagen fibers within them.
Central Canal: (aka haversian canal) contains blood vessels and nerves and runs along the central axis of the osteon.
Perforating Canal: (aka Volkmann’s Canal) channels that run perpendicular to the central canal and they connect the blood vessels and nerves of the periosteum and central canal to the central canal of other osteons.
Lacunae: small cavities that contain osteocytes
Canaliculi: small hairlike canals that connect the lacunae to each other and to the central canal. We can think of the canaliculi as the pathway through which osteocytes (that live in the lacunae) use to communicate.
What is the smallest muscle in the body that controls hair follicles and is responsible for goosebumps.
Arrector Pili
What is the function and location of Stratified Cuboidal?
What is the function and location of Dense Irregular?
Location: joint capsules
Function: provides tensile strength in many directions
List and describe all types of burns.
1st Degree Burn:
2nd Degree Burn:
3rd Degree Burn:
Describe the negative feedback loop for blood calcium regulation.
High blood calcium --> thyroid releases calcitonin --> stimulates osteoblasts to deposit calcium to build up bones
Low blood calcium --> parathyroid releases parathyroid hormone --> stimulates osteoclasts to break down bone and to put more calcium into the blood
List and describe the bone shapes.
What is the function and location of Stratified Columnar?
What is the function and location of Hyaline Cartilage?
Location: trachea, bronchi, larynx, attaches to ends of ribs, tips of nose, articulating surfaces of bones, precursor to bone
Function: support and reinforcement, resilence and cushioning, resistence of compressive stress
List and describe all types of skin cancer.
Basal Cell Carcinoma: basal cell carcinoma is the least malignant and most common form of skin cancer. Here, the stratum basale cells of the epidermis proliferate and slowly invade the dermis and hypodermis. Basal cell carcinoma is 99% curable with surgical excision.
Squamous Cell Carcinoma:
Squamous cell carcinoma is common on the scalp, ears, lower lip, and hands— areas frequently exposed to UV rays.
This cancer type involves proliferation of keratinocytes of the stratum spinosum.
An individual has a good prognosis if squamous cell carcinoma is treated by radiation therapy or surgical removal.
Melanoma: Melanoma is the most dangerous of skin cancers. It involves proliferation of melanocytes. It is highly metastatic and highly resistant to chemotherapy. It can be treated by wide surgical excision and immunotherapy.
What are the steps for Intramembranous Ossification?
What are the steps for Endochondral Ossification?
Intramembranous:
1) Ossification center
2) Calcification
3) Trabeculae forms
4) Periosteum forms
Endochondral:
1) Bone collar forms
2) Cartilage in diaphysis calcifies
3) Periosteal bud invades cavities, spongy bone forms
4) Diaphysis elongates, medullary cavity forms, secondary ossification centers form
5) Epiphyses ossify, hyaline cartilage remains only in epiphyseal plates and articular cartilages
Try to identify all tissue histology images.
Good luck :)
