A person who has cerebrospinal fluid draining from the ear probably has a fracture of the temporal bone.

<h3>What is Cerebrospinal Fluid?</h3>

All animals have cerebrospinal fluid (CSF), a transparent, colorless bodily fluid that is present in the tissue that covers their brains and spinal cords.

Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.

The ventricular system and subarachnoid space, which are located surrounding and inside the brain and spinal cord, respectively, are occupied by CSF.

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of___.
dmitriy555 [2]

A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.

A. 7.5 feet

<u>Explanation:</u>

Wave base defines the depth of the water when it is in still condition.

Wave base is half of wavelength.

Wave base = wavelength/2

Given,

Wavelength = 15 feet

So, wave base = 15 feet/2 = 7.5 feet

When the wave height is divided by wavelength then it gives the steepness of the wave.

Therefore, the wave base is 7.5feet.
