Nervous Tissues, Its Types, & Types of Membranes

nervous tissue

BLANK tissues are found in the brain, spinal cord, and nerves.

neurons

BLANK, or nerve cells, conduct nervous impulses.

neurologia

helper cells, or BLANK, support and nourish the neurons. (LARGER AND BIGGER THAN NEURONS.

epithelial membranes

• Composed of a layer of epithelial tissue and a layer of connective tissue

• Cover body surfaces and line body cavities

• Four main types: serous, mucous, synovial, and cutaneous

• Considered to be organs because these membranes are composed of more than one type of tissue

serous membranes

line body cavities that lack openings to the outside.

1. They line the thorax, abdomen and cover the organs within these cavities.

2. BLANK membranes are made up of epithelium and loose connective tissue and secrete serous fluid that acts as a lubricant.

mucous membranes

line the cavities and openings that lead to the outside of the body, including the oral and nasal cavities, and openings of the digestive, reproductive, respiratory, and urinary systems.

1. consist of epithelium and connective tissue with specialized cells that secrete mucus.

synovial membranes

1. These membranes consist of only connective tissues, and they secrete lubricating synovial fluid. (line the joint cavities)

cutaneous membrane

BLANK membrane consists of the skin (also called the integument).
