Epithelial & Integumentary System
This type of epithelium is thick, strong, and found in areas like the skin and mouth where stress is high.
What is stratified squamous epithelium?
This muscle tissue is Multi-nucleated, Striated, and Voluntary (include an example of this muscle type)
What is Skeletal muscle- Biceps
This ion is released from the sarcoplasmic reticulum and is essential for initiating muscle contraction.
What is calcium?
This tissue type is found throughout the body and functions in support, protection, and connecting structures.
What is connective tissue?
This process refers to the formation of bone through deposition of calcium salts in a matrix.
What is ossification?
These glands release their products directly into the bloodstream and do not use ducts.
What are endocrine glands?
This muscle type is striated, involuntary, and contains intercalated discs that allow coordinated contraction.
What is cardiac muscle?
This is the contractile unit of muscle, located between two Z-lines.
What is a sarcomere?
These cells produce collagen and other fibers within connective tissue.
What are fibroblasts?
These cells are responsible for building new bone tissue.
What are osteoblasts?
This layer of the skin contains adipose tissue and functions as insulation and a shock absorber.
What is the hypodermis (subcutaneous layer)?
This characteristic distinguishes skeletal muscle from smooth muscle in terms of nuclei.
What is multinucleated (skeletal muscle)?
During contraction, this protein binds to actin to form cross-bridges and generate force.
What is myosin?
This type of connective tissue stores fat and provides cushioning and insulation.
What is adipose tissue?
This type of ossification forms bone directly from mesenchymal tissue without a cartilage template.
What is intramembranous ossification?
This system includes the skin along with structures such as hair, glands, hooves, and horns, and functions as a protective barrier against water loss, microorganisms, and physical damage.
What is the integumentary system?
What muscle tissue is found in blood vessels, digestive tracts, respiratory tissues, and reproductive tissues
What is smooth muscle?
This feature of cardiac muscle allows rapid transmission of electrical signals between cells for synchronized contraction.
What are intercalated discs?
This type of connective tissue forms a flexible but strong surface that reduces friction in joints and is produced by chondrocytes.
What is cartilage?
This type of ossification involves replacing a cartilage model with bone during development.
What is endochondral ossification?
This type of glandular secretion involves the entire cell disintegrating to release its product, as seen in sebaceous glands.
What is holocrine secretion?
The Nuclei #, pattern, and control of Cardiac muscle.
What is Single nucleus (sometimes bi-nucleated), Striated, Involuntary?
If ATP is no longer available in a muscle fiber, this specific step of the contraction cycle cannot occur, causing the myosin head to remain bound to actin and preventing relaxation.
What is detachment of myosin from actin (cross-bridge release)?
This type of connective tissue is unique because it exists as a fluid matrix and functions primarily in transport.
What is blood?
During endochondral ossification, this occurs when calcification of cartilage prevents nutrient diffusion, leading to cell death and formation of an ossification center.
What is chondrocyte death due to lack of nutrients (from calcified matrix)?
