Transverse processes
27
The centrum of ninth vertebra is __________ - convex on both sides.
biconvex
28
The sacral vertebra (ninth vertebra) connects to the __________, providing support for jumping and landing
pelvic girdle
29
Acts as a shock absorber during landing. Transfers the force from the hind legs to the rest of the body.
Ninth vertebra (Sacral Vertebra)
30
The basic building block of the spinal column. It has a standard structure that helps support the body, protect the spinal cord and allow movement.
Typical Vertebra
31
The centrum of typical vertebra is __________ (concave in front, convex behind).
procoelous
32
The neural arch of typical vertebra has a ___________________.
backward-facing neural spine
33
Represents the caudal region of frog. Long and triangular in shape. Extends from the sacral vertebra and helps in transmitting forces during jumping. It provides additional support and flexibility for movement.
Urostyle
34
The apex of urostyle is pointed ____________.
backward
35
What are two frog's girdles?
1. Pectoral Girdle 2. Pelvic Girdle
36
System under pectoral girdle
1. Shoulder System
37
System under pelvic girdle
Hip system
38
System that supports the forelimbs
Shoulder system
39
System that supports the hindlimbs
Hip system
40
Present in the thoracic region. Provides attachment to the forelimbs and their muscles. Consists of two similar halves permanently attached with sternum
Pectoral Girdle
41
is a small, rod-like bone located in the upper part of the pectoral girdle. Connects the forelimbs to the skeleton. Supports movement. Acts as a bridge
Scapula
42
It is a large, flat, and cartilaginous bone attached to the scapula. Absorbs shock when landing. Provides additional support. Increases surface area for muscle attachment
Suprascapula
43
The coracoid portion comprises the _____, ________, ___________, and _________.
- clavicle, coracoid, precoracoid, epicoracoid
44
(Coracoid Portion) a slender rod
clavicle
45
(Coracoid Portion) dumb-bell shaped
coracoid
46
(Coracoid Portion) the extra support bone
precoracoid
47
(Coracoid Portion) the flexible connection
epicoracoid
48
It lies midventrally connected between the two halves of pectoral girdle.
Sternum of frog
49
Sternum of frog is composed of four parts:
1. Omosternum 2. Episternum 3. Mesosternum 4. Xiphisternum
50
It is in between the episternum and clavicle on a frog.
Omosternum
51
It is the upper part of the sternum.
Episternum
52
It is the middle part of the sternum.
Mesosternum
53
It is the lowest piece of sternum.
Xiphisternum
54
It is V-shaped and composed of two similar halves, each of which is known as osinnominatum.
Pelvic Girdle
55
Each os-innominatum of Pelvic Girdle is composed of three bones:
illium, pubis, ischium
56
A cup-shaped socket formed by ilium, pubis, and ischium
acetabulum
57
is greatly elongated and forms the major part of each os-innominatum. It runs forwards to meet the transverse process of the ninth vertebra.
Ilium
58
is much reduced. It is a triangular piece of calcified cartilage, forming the central part of the disc and a small part of the acetabulum.
Pubis
59
It is larger and slightly oval bone and both the ischia fused in the middle and form one- third part of the disc and acetabulum.
Ischium
60
It helps in supporting the body when the frog is at rest. Assists in absorbing shock when landing from a jump. Aids in pushing and climbing by providing strength and flexibility. Works with muscles to allow movement of the forelimbs.
Humerus
61
single bone in a frog’s forearm, formed by the fusion of two bones: radius and ulna
Radio-Ulna
62
Supports the forearm and absorbs impact when landing. Allows movement of the forelimbs for climbing and grasping. Provides attachment points for muscles, helping in locomotion.
Radio-ulna
63
These are small bones located in the wrist area.
Carpals
64
What are the two carpals?
Proximal row and distal row
65
Carpal that is closer to the forearm
Proximal row
66
Carpal that is closer to the fingers
Distal row
67
The first metacarpal is _________ , meaning it small and does not have a finger attached to it.
rudimentary
68
These are small bones that make up the fingers of a frog's hand. These bones provide support, flexibility, and movement to the frog's forelimbs.
Phalanges
69
It is the thigh bone of a frog and is one of the strongest and longest bones in its body.
Femur
70
The proximal swollen end of femur is called the _______, and the distal end forms a ______.
head, condyle
71
It is the lower leg bone in a frog's hindlimbs. It forms a bridge between the femur and foot bones.
Tibio-fibula
72
A tibio-fibula's single bone is commonly known as
shinbone
73
refers to the ankle region of a frog’s hindlimbs.
Tarsus
74
Tarsus is made up of two long bones:
1. Astragalus or tibiale 2. Calcaneum or fibulare
75
Inner tarsus
Astragalus or tibiale
76
Outer tarsus
Calcaneum or fibulare
77
refers to the foot bones that connect the ankle (tarsus) to the toes (phalanges) in a frog’s hindlimbs.
Metatarsus
78
Frogs have _________ metatarsal bones, one for each toe.
five
79
The toe bones in a frog's hindlimbs. They play a crucial role in locomotion, survival, assist in gripping and climbing.
