Heres a long answer,hope you don't mind :) A frog's forelegs, also called arms, contain humerus, radius and ulna bones similar to those of a human's. However, a frog's radius and ulna are fused together. Frogs' upper legs contain a femur, and its lower leg bones, the tibia and fibula, are fused together.
Frogs typically have four toes on their front legs and five on their back legs, with lengths varying by different species. Tree frogs who do a lot of climbing and aquatic frogs who require webbed toes for efficient swimming tend to have very long digits. Frogs that live in the mud typically have shorter toes that they utilize as shovels.
The skull of a frog contains five bones and it is connected directly to the spine without a neck vertebrae. At the terminus of the spine, a frog's vertebrae are fused together into a single bone. Due to the lack of ribs, a frog's pelvis is able to slide up and down its spine. This skeletal adaptation is thought to increase jumping ability.
Answer:
Cushing's syndrome
Explanation:
Prolonged hypersecretion of glucocorticoid hormones by the adrenal gland causes a hormonal imbalance where the person begins to accumulate fat and lose bone and muscle mass.
Remember, one of the most important glucocorticoid hormone is cortisol, also known as the stress hormone, it usually helps us respond to conditions that are difficult for our body and where we need to use our strength and mental dexterity, when this hormone is elevate, we can respond to stress situations more easily. It helps us activate all the metabolism, as a result, we need to use more energy.
If cortisol remains elevated all day, despite not making physical and mental strength, our body will think it needs to eat, so people with this syndrome are always hungry, and accumulate fat. Thus leading to the appearance of the symptoms of the syndrome.
Answer:
- Neurons that receive information from our sensory organs (e.g. eye, skin) and transmit this input to the central nervous system are called afferent neurons.
- Neurons that send impulses from the central nervous system to your limbs and organs are called efferent neurons.

Answer:
b. di uses across a synaptic cleft from a neuron to a muscle cell.
Explanation:
A neurotransmitter is di uses across a synaptic cleft from a neuron to a muscle cell. Neurotransmitters are chemicals which enable neurotransmission. In reaction to an impulse a motor neuron axon secretes a neurotransmitter and causes the muscle fiber to contract. It is a chemical messenger which passes on the signals across the chemical synapse.
