Cell Structure & Function
This cellular structure is responsible for synthesizing proteins and can be found floating freely or attached to the rough ER.
What are ribosomes?
This tissue type covers body surfaces and lines internal cavities and organs.
What is epithelial tissue?
Facial development occurs primarily during these weeks of gestation.
What are weeks 4 to 7?
Tooth development begins with this structure, formed by the oral epithelium.
What is the dental lamina?
The mixed dentition phase typically occurs between these ages.
What are 8 to 12 years?
This organelle produces ATP and is known as the powerhouse of the cell.
What is the mitochondrion?
This type of connective tissue includes blood and lymph, with a fluid matrix.
What are special connective tissues?
This arch gives rise to the muscles of mastication and the mandible.
What is the first pharyngeal arch (mandibular arch)?
The stages of tooth development, in order, are:
What are bud, cap, and bell?
The union of two bones separated by cartilage is known as this.
What is synchondrosis?
This structure contains the genetic material and is the control center of the cell.
đźź© What is the nucleus?
Cardiac muscle is unique among muscle types because it contains these specialized connecting structures.
What are intercalated discs?
The failure of fusion between the medial nasal and maxillary processes can result in this malformation.
What is a cleft lip?
This enamel-producing cell functions after a layer of dentin is laid down.
What is an ameloblast?
The periodontal ligament attaches these two surfaces together.
What are alveolar bone and cementum?
This part of the plasma membrane is hydrophobic and helps maintain the barrier between the cell’s internal and external environment.
What are the phospholipid tails?
This tissue type is responsible for transmitting electrical signals throughout the body.
What is nervous tissue?
The thyroid gland originates from this structure at the junction of the body and base of the tongue.
What is the foramen cecum?
The root sheath responsible for shaping roots is known as this.
What is Hertwig’s epithelial root sheath?
This type of bone is found between the roots of multirooted teeth.
What is interradicular bone?
These organelles are responsible for digesting worn-out cellular components and can contribute to diseases like Tay-Sachs when malfunctioning.
What are lysosomes?
Connective tissue proper can be classified into these three categories.
What are dense, loose, and loose with special properties?
These three facial processes merge to form the upper lip.
What are the two maxillary processes and the medial nasal process?
Tomes’ processes are first visible during this stage of ameloblast differentiation.
What is the secretion stage?
Accessory root canals connect these two structures.
What are the pulp and the periodontal ligament?
