Cheetah neurological adaptations

Cheetahs (And other cats) have enlarged betz cells (Or gigantopiramidal motoneurons M1) in the motor cortex and muscle fibers that they innervate, compared to other mammal taxons.

Cheetahs in particular have longer dendrites and more numerous dendritic segments than leopard of similar size.

This would be an adaptation for its extreme locomotion, to match type IIx muscle fibers predominants in cats.

Grammatical errors

This edit request has been answered. Set the |answered= or |ans= parameter to no to reactivate your request.

The first paragraph under "Reproduction and Life Cycle" has grammatical issues. The paragraph's first few sentences read: "Cheetahs are induced ovulators and can breed throughout the year. Females can have their first litter at two to three years of age. Polyestrous, females have an oestrus ("heat") cycle is 12 days long on average, but it can vary from three days to a month. A female can conceive again after 17 to 20 months from giving birth, or even sooner if a whole litter is lost." These sentences have grammatical errors and should be changed to the following: "Cheetahs are induced ovulators and can breed throughout the year. Females can have their first litter at two to three years of age. As cheetahs are polyestrous, females have an oestrus ("heat") cycle that is 12 days long on average, but it can vary from three days to a month. A female can conceive again 17 to 20 months after giving birth, or even sooner if a whole litter is lost." Please consider these corrections. FireflyBuffet (talk) 18:12, 3 October 2024 (UTC)

Suggested edit

"The physiological reasons for speed in cheetahs are:

• A cool nose and enlarged respiratory passages that allow it to inhale and exhale more air with each breath, which helps dissipate body heat and absorb more oxygen."

I suggest delete this last part for reasons for cheetah speed ("..... and absorb more oxygen."), as this especies achieves its muscle power primarily by anaerobic-based ways.

The activity of the enzyme Lactate Dehidrogenase (LDH), an indicator of glycogen utilization and glycolisis (And anaerobic activity in general), is high, up to 6 times higher in the cheetah than in a human.

LDH activity is also 6 times higher in the muscle fibers of caracal.

For comparison, LDH activity is up to 3 times higher in the greyhound than in a human.

The Vastus lateralis muscle of the greyhound contains 76 % of oxidative–glycolytic fast–twitch muscle fibers (Type IIa).

The same muscle of the cheetah contains 76 % of glycolytic fast-twitch muscle fibers (Type IIx).

Type IIx muscle fibers, although they deplete its energy more quickly, generate faster and more powerful contractions than type IIa muscle fibers.

And so, therefore, a higher LDH activity means a higher glycolytic capacity, which means more muscle power and therefore more speed and acceleration.

Muscle power obtained anerobically.

Furthermore, aerobic enzyme activity is usually low in felids in general (Including the cheetah).
