Muscle diferences between sexes.

[edit]

In a paper published this year, little difference was seen between the sexes of cheetahs in terms of proportion of muscle fibre types (especially type IIx) and anaerobic LDH enzyme activity. Contrary to humans, where females have a much lower LDH enzyme activity than males, the same for myosin heavy chain isoform IIx content, although the proportion of type IIx muscle fibres was equal between human males and females. This may explain the differences in athletic performance between human males and females, and why both male and female cheetahs appear to run equally fast.

Cheetah neurological adaptations

[edit]

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

[edit]

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)[reply]

@FireflyBuffet: This paragraph has been revised since your request was opened. Do you still have any suggestions to improve the grammar? Anon126 (notify me of responses! / talk / contribs) 23:13, 3 October 2024 (UTC)[reply]
