Document Summary

Anatomical position: face, palms, feet forward (thumbs outward) Axial region: everything but the limbs (head, neck, trunk) Cranial: toward the head vs. caudal: toward tail end. Proximal: apart of appendage close to attachment, toward body. Distal: part of appendage farther from attachment, away from body. Ipsilateral: on same side vs. contralateral: on opposite sides. 4 basic tissue types: epithelium, connective tissue, muscle, nervous. Smooth er makes steroid hormones and lipid metabolism. Lysosomes: breaks stuff down with digestive enzymes. Intermediate filaments: extends across entire cell, medium sized diameter, high tensile strength (resists pulling, most permanent/stable, specific for each type of cell. Nucleus brain of cell/ reproductive center/ library of dna. Tight junction: prevents diffusion across tissue through extracellular space. Gap junction: direct passageway from one cell to another. Epithelium: tissue that covers a body surface or lines a body cavity. Specialized contacts packed tightly so they form tight junctions (controls exchange of materials with the environment)
