This unusually lengthy mating is due to the physical nature of the male's erect penis, which has backwards-pointing spines along most of its length. [20] Fossa mating includes a copulatory tie, [15] which may be enforced by the male's spiny penis. [20] The tie is difficult to break if the mating session is interrupted. [15]
The fossa (Cryptoprocta ferox) is a smaller relative of C. spelea that still survives.. Although some morphological differences between the two fossa species have been described, [17] these may be allometric (growth-related), and in their 1986 Mammalian Species account of the fossa, Michael Köhncke and Klaus Leonhardt wrote that the two were morphologically identical. [18]
The Malagasy or striped civet (Fossa fossana), also known as the fanaloka (Malagasy, [fə̥ˈnaluk]) or jabady, [5] is an euplerid endemic to Madagascar. [6] It is the only species in genus Fossa . The Malagasy civet is a small mammal , about 47 centimetres (19 in) long excluding the tail (which is only about 20 centimetres (7.9 in)).
In anatomy, a fossa (/ ˈ f ɒ s ə /; [1] [2] pl.: fossae (/ ˈ f ɒ s iː / or / ˈ f ɒ s aɪ /); from Latin 'ditch, trench') is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). [3]
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development. Sexual dimorphism is a term for the ...
The Keros classification is a method of classifying the depth of the olfactory fossa. The depth of the olfactory fossa is determined by the height of the lateral lamella of the cribriform plate. Keros in 1962, classified the depth into three categories. [3] type 1: has a depth of 1–3 mm (26.3% of population)
The posterior cranial fossa is the part of the cranial cavity located between the foramen magnum, and tentorium cerebelli. It is formed by the sphenoid bones , temporal bones , and occipital bone .
The temporomandibular joints are the dual articulation of the mandible with the skull. Each TMJ is classed as a "ginglymoarthrodial" joint since it is both a ginglymus (hinging joint) and an arthrodial (sliding) joint, [42] and involves the condylar process of the mandible below, and the articular fossa (or glenoid fossa) of the temporal bone ...
