Abstract. The average ultimate tensile strength, loaded in the direction of the long axis, of the compact bone of 15 specimens taken from the parietal bone of adult human embalmed cadavers was 10,230 lb/in.

What happens when the right parietal lobe is damaged?

Damage to the right parietal lobe can result in neglecting part of the body or space (contralateral neglect), which can impair many self-care skills such as dressing and washing. Right side damage can also cause difficulty in making things (constructional apraxia), denial of deficits (anosagnosia) and drawing ability.

What happens if the parietal lobe is damaged?

Parietal Lobe, Right – Damage to this area can cause visuo-spatial deficits (e.g., the patient may have difficulty finding their way around new, or even familiar, places). Parietal Lobe, Left – Damage to this area may disrupt a person’s ability to understand spoken and/or written language.

What does the right parietal lobe of the brain control?

The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain’s primary sensory area, a region where the brain interprets input from other areas of the body.
