Cell Membrane Transport, Exocytosis/Endocytosis, and Epithelium (Video Lecture)

Flashcards covering carrier-mediated transport, cortical processing of sensory input, endocytosis/exocytosis, neurotransmitter release, and epithelial tissue layering as discussed in the video notes.

What is carrier-mediated transport?

A specialized, saturable transport mechanism that uses membrane carrier proteins to move specific substances across the cell membrane.

Where does visual information go in the brain to be processed?

To the cortex, specifically the visual cortex in the occipital lobe.

What is exocytosis?

The process by which vesicles fuse with the plasma membrane to release their contents outside the cell (e.g., neurotransmitter release like acetylcholine).

What is endocytosis?

The process by which the cell takes in material via vesicle formation from the plasma membrane.

What does monolayer mean in epithelial tissue?

A single layer of cells (simple epithelium).

What does stratified mean in epithelial tissue?

Multiple layers of cells, providing thicker, often protective tissue.

How is acetylcholine released at a synapse?

Via exocytosis of acetylcholine-containing synaptic vesicles into the synaptic cleft.
