Histology
A single layer of flat cells that allow for the rapid diffusion of substances.
What is simple squamous epithelial tissue?
An organelle where protein synthesis occurs.
What is a ribosome?
Bone cell that builds up bone.
What is an osteoblast?
Increases heart rate and blood pressure
What is the sympathetic nervous system?
The top layer of the epidermis containing dead keratinocytes.
What is the stratum corneum?
A type of tissue found in the ducts of sweat glands and is made up of multiple cell layers.
What is stratified cuboidal epithelial tissue?
The unassisted movement of small, non-polar or lipid-soluble particles through the lipid bilayer of the cell membrane (example: Oxygen)
What is simple diffusion?
The carpal bones are this shape.
What are short bones?
Has long preganglionic fibers and short postganglionic fibers
What is the parasympathetic nervous system?
When the skin turns a bluish color due to lack of oxygen.
What is cyanosis?
This tissue provides the supportive framework for lymphatic organs and appears mesh-like under the microscope.
What is reticular tissue?
This cation is more concentrated outside of the cell.
What is sodium?
Bone ossification that forms the flat bones like the skull and clavicles.
What is intramembranous ossification?
The neurotransmitter released by preganglionic neurons in both the parasympathetic and sympathetic nervous system.
What is acetylcholine?
What is the papilla?
A type of tissue that provides tensile strength in one plane of movement. Found in tendons and ligaments.
What is regular dense connective tissue?
This process occurs in the nucleus of the cell and copies genetic instructions from DNA to RNA.
What is transcription?
The plasma membrane of a muscle cell.
What is the sarcolemma?
A gland that releases epinephrine and norepinephrine in response to sympathetic activation.
What is the adrenal gland?
Layer of the dermis that contains dense irregular connective tissue.
What is the reticular layer?
A tissue found in the pubic symphysis and intervertebral discs for shock absorption.
What is fibrocartilage?
Chromatids separate towards opposite poles in this phase.
What is anaphase?
A long strand of protein that covers the binding sites on actin when the muscle is relaxed.
What is tropomyosin?
Contain the cell bodies of sensory neurons.
What are dorsal root ganglions?
Layer of the epidermis only found in thick skin.
What is the stratum lucidum?
