Q

nervous system (5)

A

cells called neurons

axons transmit impulses away from cell body
dendrites transmit impulses to cell body

axon is enclosed by a schwann cell (produce myelin sheath)
a synapse is the point at which a nerve impulse is transmitted

Q

motor neuron(5)

A

dendrite (cell body)
nucleus (in dendrite)
axon hillock (joins dendrite to axon)
Schwann cell (many create myelin sheath, cover exon)
terminal branches (connect to axon on other side)

Q

hyaline(3)

A

prevents friction, end of bones, between ribs and sternum

17
Q

fibrocartilage (4)

A

enlarged joint sockets and protects tendons where they have to slide over the bone, between pubic bones, at shoulder and hip, invertebral discs and edges of sockets of ball

18
Q

elastic cartilage(3)

A

external ear, epiglottis, eustachian tubes

19
Q

epithelium(1)

A

covers the surface of the body

20
Q

squamous epithelium(4)

A

thin, large flattened irregularly shaped. Allows for nutrients and gasses to diffuse easily, in Oesophagus.

21
Q

cuboidal epithelium (4)

A

tightly packed, cube shaped with large central nuclei. Great for secretion and absorption of substances, in lining of glands.

22
Q

columnar epithelium (5)

A

elongated, column shaped. Secretes mucus, absorbs food; protects and supports underlying tissue, In digestive tract

23
Q

ciliated columnar epithelium (5)

A

has fine hair on the column shape. Beats mucus along air passage way, cilia also move ova in oviducts, helps move cerebrospinal fluid along central canal of spinal cord. In nose.
