**Question:**
Which of the following impact intracranial pressure: (select all that apply) 

**Options:**
- [ ] Brain tissue
- [ ] CSF Volume
- [ ] Skull circumference
- [ ] Cerebral blood volume 

**Explanation:**
In this question, you are asked to identify which factors affect intracranial pressure. Intracranial pressure (ICP) is the pressure within the skull, and it can be influenced by various components inside the cranium. Typically, these components include:

1. **Brain tissue**: The volume of the brain tissue itself can have a significant effect on ICP.
2. **CSF (Cerebrospinal Fluid) Volume**: The amount of cerebrospinal fluid present within the brain and spinal cord plays a crucial role in determining ICP.
3. **Skull circumference**: This option might seem relevant, but in most cases of studying given population statistics, individual variations of skull circumference do not practically impact ICP in clinical scenarios.
4. **Cerebral blood volume**: The volume of blood within the cerebral vessels can also influence ICP.

When considering factors impacting intracranial pressure, the physiological determinants are generally focused on the compartments contained within the skull: brain tissue, cerebrospinal fluid volume, and cerebral blood volume.

It’s important for students to understand these components for clinical assessments and managing conditions related to intracranial pressure.
