Adipose tissue is a type of loose connective tissue that stores fat for energy, insulation, and cushioning.
Apocrine glands release secretions by budding off a portion of the cell's cytoplasm.
Blood is a connective tissue composed of cells suspended in plasma, transporting oxygen, nutrients, and waste.
Bone is a dense connective tissue that provides structural support and protection, composed mainly of osteocytes.
Cardiac muscle is an involuntary, striated muscle found only in the heart, responsible for pumping blood.
Cartilage is a flexible connective tissue made of chondrocytes embedded in a firm matrix.
Chondrocytes are the cells that produce and maintain the cartilage matrix.
Connective tissue supports, connects, or separates different types of tissues and organs in the body.
Dense connective tissue contains tightly packed collagen fibers providing strong connections, e.g., tendons and ligaments.
DNA stores genetic information used for cell function and inheritance.
Epithelial tissue covers body surfaces and lines cavities, providing protection and absorption.
Holocrine glands release secretions by the entire cell disintegrating and becoming part of the secretion.
Loose connective tissue has a loose arrangement of fibers and cells, providing cushioning and support.
Merocrine glands secrete products by exocytosis without losing cellular material.
mRNA carries genetic code from DNA to ribosomes for protein synthesis.
Muscle tissue is specialized for contraction to produce movement.
Nervous tissue transmits electrical signals for communication within the body.
Neurons are nerve cells that transmit impulses through electrical and chemical signals.
Osteocytes are mature bone cells that maintain the bone matrix.
Ribosomes are cellular structures where proteins are synthesized.
rRNA is ribosomal RNA, a component of ribosomes essential for protein synthesis.
Simple cuboidal epithelium consists of a single layer of cube-shaped cells involved in secretion and absorption.
Simple squamous epithelium is a single layer of flat cells allowing rapid diffusion and filtration.
Skeletal muscle is voluntary, striated muscle attached to bones for movement.
Smooth muscle is involuntary, non-striated muscle found in walls of internal organs.
Stratified columnar epithelium has multiple layers with tall, column-shaped cells on the surface for protection.
Stratified cuboidal epithelium consists of several layers of cube-shaped cells, mainly for protection.
Stratified squamous epithelium has multiple layers of flat cells protecting against abrasion.
Transcription is the process of copying DNA into mRNA in the nucleus.
tRNA transfers specific amino acids to ribosomes during protein synthesis.
Transitional epithelium is a specialized tissue that stretches, found in the urinary bladder.
Translation is the process where ribosomes synthesize proteins using mRNA as a template.
