Front

What is the primary histological difference between compact bone and spongy bone?

Back

Compact bone is smooth and solid, organized into osteons, while spongy bone consists of an open lattice of interconnecting bony struts called trabeculae.

Front

Identify the muscle corresponding to the number 1 on the human body diagram.

Back

The muscle corresponding to number 1 is the rectus abdominus.

Front

What are the three fundamental parts of a chemical synapse?

Back

The three fundamental parts of a chemical synapse are the presynaptic terminal, synaptic cleft, and postsynaptic membrane.

Front

What is a specific physiological response caused by the Sympathetic Nervous System (SNS) during stress?

Back

Dilation of the airways to increase the volume of air inhaled and exhaled.

Front

What bones are included in the Axial Skeleton?

Back

The Axial Skeleton includes the skull, vertebral column, and rib cage.

Front

Define compact bone.

Back

Compact bone is the dense outer layer of bone that provides strength and structure, organized into units called osteons.

Front

What is spongy bone and where is it found?

Back

Spongy bone is the inner layer of bone that has a porous structure, found at the ends of long bones and in the interior of others.

Front

What is the role of the presynaptic terminal in a chemical synapse?

Back

The presynaptic terminal releases neurotransmitters into the synaptic cleft to transmit signals to the postsynaptic membrane.

Front

Explain the function of the synaptic cleft.

Back

The synaptic cleft is the small gap between the presynaptic terminal and the postsynaptic membrane where neurotransmitters diffuse.

Front

What is the function of the postsynaptic membrane?

Back

The postsynaptic membrane contains receptors that bind neurotransmitters, initiating a response in the postsynaptic neuron.
