The space between two neurons is called:
A synapse
The body is supported by:
Bone
The tissue that protects some internal organs from mechanical injury is:
Bone
Osteocytes are cells of ___, and are found in a matrix made primarily of __.
Bone/calcium salts
The part of a neuron that carries impulses toward the cell body is the:
Dendrite
The tissue that sweeps pathogens up and out of the trachea is:
Ciliated epithelium
The visceral pleura is found:
Covering the lungs
The connective tissue that forms tendons is:
Fibrous connective tissue
The tissue that forms ligaments is:
Fibrous connective tissue
Endocrine glands have __ and secrete ___.
No ducts/hormones
The heart is made of __ muscle, which ___.
Cardiac/pumps blood
The tissue that keeps the trachea an open airway is:
Cartilage
The tissue that provides a smooth surface in joints is:
Cartilage
Chondrocytes are cells of __, and are found in matrix that has no __.
Cartilage/capillaries
The connective tissue that stores potential energy is:
Adipose tissue
Mucous membranes are found in:
All tracts
The part of a neuron that contains the nucleus and is essential for the life of the neuron is the:
Cell body
The part of a neuron that carries impulses away from the cell body is the:
Axon
The myelin sheath of peripheral neurons is formed by __ to provide __ for neurons.
Axons/electrical insulation
At synapses, nerve impulse transmission is accomplished by:
Chemical neurotransmitters
Platelets in the blood are important for:
Blood clotting
Salivary glands secrete saliva into ducts, therefore, they are called __ glands.
Exocrine
The purpose of microvilli in the small intestine is to:
Increase the surface area for absorption
With a deficiency of white blood cells, the body will soon suffer from:
Infections
The function of Schwann cells is to form the __ of peripheral neurons.
Myelin sheath
The function of red blood cells is to transport __ bonded to the protein __.
Oxygen/hemoglobin
The serous membrane that lines the thoracic cavity is the:
Parietal pleura
The function of smooth muscle is the small intestine is:
Peristalsis
The serous membrane that lines the abdominal cavity is the:
Peritoneum
The fluid that transports nutrients in the blood is:
Plasma
Red blood cells are produced in the:
Red bone marrow
The functions of nerve tissue include:
Sensation, movement, & learning
The fluid that prevents friction between the pleural membranes is:
Serous fluid
The tissue that is thin enough to permit diffusion of gases in the lungs is:
Simple squamous
Fibrous connective tissue forms ligaments because it is:
Strong
Stratified squamous epithelium makes up the epidermis of the skin because:
The surface cells are dead and prevent water loss. The lower cells are capable of mitosis to replace cells lost from the surface.
The tissue that lines the urinary bladder, in which the surface cells flatten as the bladder expands, is:
Transitional epithelium
The serous membrane that covers the surface of the heart is called the:
Visceral pericardium
The cells that destroy pathogens that have entered the body are the:
WBC's
